JPanel to be displayed center of the screen - GlassPane and JFrame

Question

Hi,
I have a JFrame whereby I display a JPanel which has two buttons. When the JPanel is displayed, focus must be on the JPanel and user must select something on the JPanel before focus goes back to the JFrame. I've used a glassPane to do
which works correctly however, my JPanel is coming up at the top of the JFrame rather than in the middle. I've tried panel.setLocation but this doesn't seem to be working.
Hope you can help,
Thanks
some of the code:
JFrame myFrame = new JFrame();
JPanel glassPanel = new JPanel();
glassPanel.setOpaque(false);
JPanel confirmPanel = createNewConfirmPanel();
glassPanel.add(confirmPanel);
myFrame.setGlassPane(myFrame);
glassPanel.setVisible(true);
in createNewConfrimPanel() I call setLocation(x,y)

Thanks db.
Just doing some more debugging and my problem is in this class -
public class RoundedPanel extends JPanel {
public RoundedPanel(){
super();
public boolean isOpaque() {
return false;
public void paintComponent(Graphics g) {
super.paintComponent(g);
Graphics2D g2 = (Graphics2D) g;
Shape rect = new RoundRectangle2D.Float(0,0,getWidth()-5,getHeight()-5, 50,50);
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
Paint paint = new GradientPaint(0,0,Color.white, 0,getHeight(), Color.lightGray);
g2.setPaint(paint);
g2.fill(rect);
g2.setColor(Color.black);
g2.draw(rect);
My panel extends RoundedPanel above. My problem is in paintComponent..I can't see where it is setting location.
Thanks
