SpinSlider may be a useful example.

Appendix: Here is an example using a suitable format string for JSpinner.NumberEditor.

Addendum: you can change the color of the slider by overriding paintTrack(), as shown here .

import java.awt.EventQueue;
import java.awt.FlowLayout;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JSlider;
import javax.swing.JSpinner;
import javax.swing.SpinnerNumberModel;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;

/** @see https://stackoverflow.com/questions/6067898 */
public class SpinSlider extends JPanel {

    public static void main(String args[]) {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                JFrame f = new JFrame("SpinSlider!");
                f.add(new SpinSlider());
                f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                f.pack();
                f.setVisible(true);
            }
        });
    }

    public SpinSlider() {
        this.setLayout(new FlowLayout());
        final JSpinner spinner = new JSpinner();
        final JSlider slider = new JSlider();
        slider.addChangeListener(new ChangeListener() {
            @Override
            public void stateChanged(ChangeEvent e) {
                JSlider s = (JSlider) e.getSource();
                spinner.setValue(s.getValue());
            }
        });
        this.add(slider);
        spinner.setModel(new SpinnerNumberModel(50, 0, 100, 1));
        spinner.setEditor(new JSpinner.NumberEditor(spinner, "0'%'"));
        spinner.addChangeListener(new ChangeListener() {
            @Override
            public void stateChanged(ChangeEvent e) {
                JSpinner s = (JSpinner) e.getSource();
                slider.setValue((Integer) s.getValue());
            }
        });
        this.add(spinner);
    }
}

//Some other code, adding the the slider, text box (and other stuff) to the application

In Java Swing, you can use JSlider (which already has the desired model and behavior) and then customize its user interface
