title: Opening a new GUI window on a main GUI using GUI builder on netbeans
body: <p>I am playing about with GUI builder and i was wondering if there is an easy way to open the register window through the current main window (in reference to the page below). I am trying to do this through the menu bar.</p>
  
  <p>I've been trying all day, because GUI Builder generates some code, its not possible to edit this code.</p>
