I'm assuming you are talking about Tkinter here:

If so, your 'menubar' is a Tk menu, with cascade buttons in it.  It is 
also possible to attach a "command" button to it:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
import Tkinter
Tk = Tkinter

def output_func():
    print "T.I.S.M. is a fine Aussie band."
    return

root = Tk.Tk()  #This opens a Toplevel()

menubar = Tk.Menu( root )
menubar.add_command( label='T.I.S.M.', command=output_func )

root.configure( menu=menubar )   #Attach menubar to the Toplevel

root.mainloop()
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

And if that doesn't work for you, then use the 'bind' command on the 
button or widget that you want to trigger the exit, and look for 
"<ButtonPress-1>" events.  Attach that to an exit function.

Other window toolkits should have analogous methods of doing this.

P.S. In my version, I just reuse the root Toplevel; you can also attach 
a menubar at creation time.
