FlowLayout in Swing

This is my layout.

enter image description here

Two switches should be below the welcome mark.

like this:

__________________________
|                        | 
|        WELCOME         |
|         *  *           |
|                        |
|                        |
|                        |
|________________________|

two asterisks are switches.

My code is:

northpanel.setLayout(new FlowLayout(FlowLayout.CENTER));
northpanel1.setLayout(new FlowLayout(FlowLayout.CENTER));


northpanel.add(welcome);  //this welcome text label

northpanel1.add(r1);   //this radio 1
northpanel1.add(r2);   //this radio 2


add(northpanel,BorderLayout.NORTH);
add(northpanel1,BorderLayout.NORTH);

It looks like this (although you need to resize it a bit):

You should use GridLayout OR GridBagLayout instead of Flow-layout. First install the GridBagLayout from the north panel, and then add the necessary components, say, your radio buttons and the welcome shortcut. For more information, you can refer to here .
