Swing/EDT - Static vs Instance?

When Sun published the recommendation to create and modify all Swing
components in the EDT, I changed the way I write my GUI apps to mimic
the example in the Java Tutorial. The Tutorial example does the GUI
creation in a static method called on the EDT from the main method.
Before this recommendation we all just extended JFrame and created our
GUIs in the constructor. Using the static method required some changes
to the coding of things like action listeners. None of them
insurmountable just different. But why the static method? Why couldn't
we just extend JFrame as usual and instantiate it on the EDT? I'm not
sure why I didn't think of this before but somebody else's post on
another subject got me to thinking. So I'm curious how others create
their Swing GUIs. Do you follow the Tutorial, use the old method or
something else?

Thanks,

         JFrame f = new JFrame("test7");
         f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
         f.setSize(200,200);
         f.setVisible(true);
         System.out.println(EventQueue.isDispatchThread());

     public static void main(String[] args) {
         Runnable r = new Runnable() {

                 createGUI();
             }
         };
