You can show panel using an undecorated JDialog

    public static void main(String args[])
    {
         final JDialog bwin = new JDialog();
         bwin.addWindowFocusListener(new WindowFocusListener()
         {
             @Override
             public void windowLostFocus(WindowEvent e)
             {
               bwin.setVisible(false);
               bwin.dispose();
             }

             @Override
             public void windowGainedFocus(WindowEvent e)
             {
             }
         }); 

        bwin.setUndecorated(true);

        JLabel label = new JLabel("About");

        JPanel panel = new JPanel();
        panel.setLayout(new BorderLayout());
        panel.add(label);
        panel.setPreferredSize(new Dimension(200,200));

        bwin.add(panel);
        bwin.pack();
        bwin.setVisible(true);
    }

I guess JDialog is what you need.

See this for details : How to Make Dialogs

Here is a sample :

enter image description here

import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JOptionPane;

public class CreateDialogFromOptionPane {

    public static void main(final String[] args) {
        JFrame parent = new JFrame();
        JButton button = new JButton();

        button.setText("Click me to show dialog!");
        parent.add(button);
        parent.pack();
        parent.setVisible(true);

        button.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                JOptionPane optionPane = new JOptionPane("Is this what you need?", JOptionPane.QUESTION_MESSAGE,JOptionPane.YES_NO_OPTION);
                JDialog dialog = optionPane.createDialog("Dialog");
                dialog.setVisible(true);
            }
        });
    }
}

first you would need to create an event handler for your button, then in your handler you should create your panel and make it visible. if you want more of a popup you should use like:

JOptionPane.showMessageDialog(frame, "This is my message");

that will create a warning message, you could also create your own costume dialog i would suggest reading this
