Swing/AWT/SWT :: Factory Design Pattern With Swing JDialog

Is it a good idea to use the factory design pattern for say if I needed to create four different JDialogs for the same parent frame?

factory design interface
package client;
public interface Dialog {
void getInstanceOf ();
void initComponents ();
}

One of the four JDialog class would look something like this without the comments.

package client;
import javax.swing.JDialog;
@SuppressWarnings("serial")
public class AddCustomerDialog extends JDialog implements Dialog{
public AddCustomerDialog () {
//Some stuff goes here to set the settings for JDialog instance

[code]....

Of course you would have your factory class
