The same answer : JOptionpane with an example :)

package experiments;

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

public class CreateDialogFromOptionPane {

    public static void main(final String[] args) {
        final 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() {
            @Override
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                String name = JOptionPane.showInputDialog(parent,
                        "What is your name?", null);
            }
        });
    }
}

Hmm it has been a little while but from what I remember...
If you want a custom window you can just make a new frame and make it show up just like you would with the main window. Java also has a great dialog library that you can check out here:

How to Make Dialogs

That may be able to give you the functionality you are looking for with a whole lot less effort.

Object[] possibilities = {"ham", "spam", "yam"};
String s = (String)JOptionPane.showInputDialog(
                    frame,
                    "Complete the sentence:\n"
                    + "\"Green eggs and...\"",
                    "Customized Dialog",
                    JOptionPane.PLAIN_MESSAGE,
                    icon,
                    possibilities,
                    "ham");

//If a string was returned, say so.
if ((s != null) && (s.length() > 0)) {
    setLabel("Green eggs and... " + s + "!");
    return;
}

//If you're here, the return value was null/empty.
setLabel("Come on, finish the sentence!");

If you do not care to limit the user's choices, you can either use a form of the showInputDialog method that takes fewer arguments or specify null for the array of objects. In the Java look and feel, substituting null for possibilities results in a dialog that has a text field and looks like this:
