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:
