A second window from an applet?

....I hope this helpsI doubt whether the OP really wants a JFrame and a JApplet together, though I could be wrong. The standard way to do what he wants (I believe ) is with a JDialog. Here's a trivial example of what I mean:
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 java.lang.reflect.InvocationTargetException;
import javax.swing.BorderFactory;
import javax.swing.JApplet;
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
public class FuJApplet extends JApplet
    public void init()
        try
            SwingUtilities.invokeAndWait(new Runnable()
                public void run()
                    // create a JPanel with JButton that goes into the
                    // JApplet's contentPane
                    JButton newDialogBtn = new JButton("New Dialog");
                    newDialogBtn.addActionListener(new ActionListener()
                        public void actionPerformed(ActionEvent arg0)
                            openNewDialog();
                    JPanel btnPanel = new JPanel();
                    btnPanel.add(newDialogBtn);
                    getContentPane().add(btnPanel);
        catch (InterruptedException e)
            e.printStackTrace();
        catch (InvocationTargetException e)
            e.printStackTrace();
    // method to create and show a new JDialog
    private void openNewDialog()
        // first create a JPanel and components that goes in the JDialog
        JLabel titleLbl = new JLabel("My New Dialog");
        titleLbl.setFont(titleLbl.getFont().deriveFont(Font.BOLD, 48));
        JButton exitBtn = new JButton("Exit");
        exitBtn.addActionListener(new ActionListener()
            public void actionPerformed(ActionEvent e)
                Window dialogWindow = SwingUtilities
                    .getWindowAncestor((JButton) e.getSource());
                dialogWindow.dispose();
        JPanel exitBtnPanel = new JPanel();
        exitBtnPanel.add(exitBtn);
        JPanel dialogPanel = new JPanel(new GridLayout(0, 1, 10, 10));
        dialogPanel.setBorder(BorderFactory.createEmptyBorder(15, 15, 15, 15));
        dialogPanel.add(titleLbl);
        dialogPanel.add(exitBtnPanel);
        // then create the JDialog and add the JPanel above, pack it, show it
        JDialog dialog = new JDialog(
            (Window) SwingUtilities.getWindowAncestor(this),
            "New Dialog",
            ModalityType.APPLICATION_MODAL);
        dialog.getContentPane().add(dialogPanel);
        dialog.pack();
        dialog.setLocationRelativeTo(null);
        dialog.setVisible(true);
