I have two ideas:
- subclass Tkinter.Button. I think that way the callback will get
your new, modified class as event.widget .

- intercept the callback when it is called, for example like this:
(not tested)

>         self.button.grid(row = r, column = c)
          self.button.bind('<Button-1>',self._callback)
          self.callback=callback
          
     def _callback(self, event):
          event.widget=self
          apply(self.callback, event)
