I'm not entirely sure what you are after here. To me it sounds better to 
create names like

"cell%i" % row * column

just for the sake of having different names, but store the cell in a 
2-dimensional list called e.g. "cells"

Then accessing the cell at x, y is simply

cells[x][y].create_text(...)

Does that make sense to you?

You can of course go for globals. Beside that, a callback can be 
anything callable. That means that you can go for something like this:

class StatefulCallable(obkect):

     def __init__(self, some_state):
         self.state = some_state

     def __call__(self, *args): # I'm not sure what comes with the callback
         print "called with args %r and state %r" % (args, self.state)


Then pass an instance of StatefulCallable as callback.
