Yes, the return code of command= callables is ignored (thus I never
code a return in those cases) -- sorry, I had dropped into Tkinter
mindset here.

>>Button(buttonsFrame, text='Squirk', command=specificSquirker)

Another nice alternative, btw, is

Button(buttonsFrame, text='Squirk', command=curry(self.squickIt, 23, 45))

Look up curry in the Python Cookbook if it only suggests Indian food to 
you...:-).
