for example:
import java.awt.BorderLayout;
import java.awt.Font;
import java.awt.GridLayout;
import java.awt.Window;
import java.awt.Dialog.ModalityType;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JApplet;
import javax.swing.JButton;
import javax.swing.JComponent;
import javax.swing.JDialog;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingConstants;
import javax.swing.SwingUtilities;
public class MyApplet extends JApplet
  public void init()
    try
      javax.swing.SwingUtilities.invokeAndWait(new Runnable()
        public void run()
          createGUI();
    catch (Exception e)
      System.err.println("createGUI didn't successfully complete");
  private void createGUI()
    getContentPane().add(new AppletPanel().getComponent());
class AppletPanel
  private JPanel mainPanel = new JPanel();
  public AppletPanel()
    JButton showDialog = new JButton("Show Dialog");
    mainPanel.add(showDialog);
    showDialog.addActionListener(new ActionListener()
      public void actionPerformed(ActionEvent e)
        JButton btn = (JButton)e.getSource();
        Window win = SwingUtilities.getWindowAncestor(btn);
        JDialog dialog = new JDialog(win, "My Dialog", ModalityType.APPLICATION_MODAL);
        dialog.getContentPane().add(new DialogPanel().getComponent());
        dialog.pack();
        dialog.setLocationRelativeTo(null);
        dialog.setVisible(true);
  public JComponent getComponent()
    return mainPanel;
class DialogPanel
  private static final int SIDE = 9;
  private JPanel mainPanel = new JPanel();
  public DialogPanel()
    JPanel btnPanel = new JPanel(new GridLayout(SIDE, SIDE, 5, 5));
    for (int i = 0; i < SIDE; i++)
      for (int j = 0; j < SIDE; j++)
        JButton btn = new JButton("[" + i + ", " + j + "]");
        btnPanel.add(btn);
    JLabel titleLabel = new JLabel("JDialogs Can Be Complex", SwingConstants.CENTER);
    titleLabel.setFont(titleLabel.getFont().deriveFont(Font.BOLD, 32));
    mainPanel.setLayout(new BorderLayout());
    mainPanel.add(titleLabel, BorderLayout.NORTH);
    mainPanel.add(btnPanel, BorderLayout.CENTER);
  public JComponent getComponent()
    return mainPanel;
}
