GUI Builder makes creating a menu bar simple. From the menu bar on the GUI Builder window, select File --> New File.
From the tool bar on the GUI Builder File window, click the Insert Menu tool button to create a panel builder where you can insert the components for your menu.

After
you create the menu, use the Preview tool button 
to preview it. For this example,
from the newly created Launch menu you can select either Property
Sheet or Wizard. The following figures illustrate what you see
when you select these menu items.
