As Ed says, you could use Python's  'exec'  - but that always feels a 
bit like cheating to me :-)

In Pythoncard, you can refer to components as either
   self.components.button4
or
   self.components["button4"]

so I'd do something like

    button_name = "button%d" % button_number
    self.components[button_name].file = "something.jpg"
