Adding JPanel to Jframe dynamically

I have a form in my Java application that is mainly designed to provide the user with a list of data from a database query. one idea was to use a table and populate each row with data from my result set. However, when developing the user interface, my team and I decided that it did not look as smooth as we wanted. Therefore, we thought that we would consider creating a custom view of the results in a panel. we wanted it to look something like this: Desired custom view

Thus, instead of table rows, it will look as shown, with one for each query on the result set.

The problem I am facing encodes this. I spent a lot of time training to add a component to JForm. since netbeans seem to have configured ui by default as grouplayout? so I developed how to add 1 panel using:

javax.swing.JLabel idLbl;
 javax.swing.JLabel jLabel1;
 javax.swing.JLabel jLabel3;
 javax.swing.JLabel jLabel5;
 javax.swing.JLabel jLabel7;
 javax.swing.JPanel jPanel1;
 javax.swing.JLabel prefContactLbl;
 javax.swing.JLabel propertyLabel;
    jPanel1 = new javax.swing.JPanel();
    jLabel1 = new javax.swing.JLabel();
    idLbl = new javax.swing.JLabel();
    jLabel3 = new javax.swing.JLabel();
    propertyLabel = new javax.swing.JLabel();
    jLabel5 = new javax.swing.JLabel();
    contactLabel = new javax.swing.JLabel();
    jLabel7 = new javax.swing.JLabel();
    prefContactLbl = new javax.swing.JLabel();

    jPanel1.setBorder(javax.swing.BorderFactory.createEtchedBorder());

    jLabel1.setFont(new java.awt.Font("Tahoma", 1, 12));
    jLabel1.setText("Enquiry Id:");
    jLabel1.setName("jLabel"+i);

    idLbl.setText("jLabel2");

    jLabel3.setFont(new java.awt.Font("Tahoma", 1, 12));
    jLabel3.setText("Property:");

    propertyLabel.setText("A property Address in some town with a postcode");

    jLabel5.setFont(new java.awt.Font("Tahoma", 1, 12));
    jLabel5.setText("Contact:");

    contactLabel.setText("A Persons Name ( 01010100011)");

    jLabel7.setFont(new java.awt.Font("Tahoma", 1, 12));
    jLabel7.setText("Prefered Contact:");

    prefContactLbl.setText("Email/Phone");

    javax.swing.GroupLayout jPanel1Layout = new javax.swing.GroupLayout(jPanel1);
    jPanel1.setLayout(jPanel1Layout);
    jPanel1Layout.setHorizontalGroup(
        jPanel1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGroup(jPanel1Layout.createSequentialGroup()
            .addContainerGap()
            .addGroup(jPanel1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
                .addGroup(jPanel1Layout.createSequentialGroup()
                    .addComponent(jLabel1)
                    .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED)
                    .addComponent(idLbl)
                    .addGap(18, 18, 18)
                    .addComponent(jLabel3)
                    .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED)
                    .addComponent(propertyLabel))
                .addGroup(jPanel1Layout.createSequentialGroup()
                    .addComponent(jLabel7)
                    .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED)
                    .addComponent(prefContactLbl)
                    .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.UNRELATED)
                    .addComponent(jLabel5)
                    .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED)
                    .addComponent(contactLabel)))
            .addContainerGap(20, Short.MAX_VALUE))
    );
    jPanel1Layout.setVerticalGroup(
        jPanel1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGroup(jPanel1Layout.createSequentialGroup()
            .addContainerGap()
            .addGroup(jPanel1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE)
                .addComponent(jLabel1)
                .addComponent(idLbl)
                .addComponent(jLabel3)
                .addComponent(propertyLabel))
            .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED)
            .addGroup(jPanel1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE)
                .addComponent(jLabel7)
                .addComponent(prefContactLbl)
                .addComponent(jLabel5)
                .addComponent(contactLabel))
            .addContainerGap())
    );

    javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
     getContentPane().setLayout(layout);
    layout.setHorizontalGroup(
        layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGroup(layout.createSequentialGroup()
            .addGap(10 , 10, 10)
            .addComponent(jPanel1, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
                 .addContainerGap(100, Short.MAX_VALUE))
    );

    layout.setVerticalGroup(
        layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGroup(layout.createSequentialGroup()
            .addContainerGap()
            .addComponent(jPanel1, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
            .addContainerGap(570, Short.MAX_VALUE))
    );

The main problem I ran into is adding more than 1 dynamically. I am completely unsure how to do this, since all I can find is to install the layout without updating it. And I can’t establish how much .addcomponent is like its dynamics. Actually confused how to do this.

Sorry if it's hard to understand what I'm trying to understand, but thinking about him is a nightmare.

Instead, I would probably use a vertical BoxLayout. After adding each panel, be sure to reinstall () the parent panel.
