Some tips:
Need to make visible your JFrame calling setVisible(true)
Instead of add(pane) you can use setContentPane(pane) replacing the default container used as content pane.

Create your GUI objects in the Event Dispatch Thread using SwingUtilities.invokeLater()
Avoid extend from JFrame unless you need to add some functionality. If that's not the case, use a JFrame variable or class member instead.
You need to set it to visible. Use:
setVisible(true)
