I guess JDialog is what you need.

See this for details : How to Make Dialogs

Here is a sample :

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

public class CreateDialogFromOptionPane {

    public static void main(final String[] args) {
        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() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                JOptionPane optionPane = new JOptionPane("Is this what you need?", JOptionPane.QUESTION_MESSAGE,JOptionPane.YES_NO_OPTION);
                JDialog dialog = optionPane.createDialog("Dialog");
                dialog.setVisible(true);
            }
        });
    }
}
