If you need for it to popup a Dialog (or a new frame), you write the following in the class with the button:


public Example exampleDialog;
//Example is the name of the new class, where the dialog configuration would be placed

exampleDialog = new Example();

//Creating a new Dialog

private class Controller implements ActionListener {

public void actionPerformed(ActionEvent e) {

if (e.getSource() == yourbutton ){
exampleDialog.setVisible(true);
}
//When the button is clicked, it will open a new Dialog.

//In the Example we class, you just create a new frame, with necessary options.

public class Example extends JDialog {

public ConferenceDialog(){

this.setDefaultCloseOperation(JFrame.DISPOSE_ON_CL OSE);
this.setModal(true);
this.setTitle("title");
this.setLocation(150, 150);
this.setSize(465, 405);
this.setResizable(false);

//..and so on

So when you click on the button, it will open a new Dialog frame. Hope it helps.
