There are two ways to do this:

  1) Creating lists of StringVars, and modify them using the
     set() method.

  2) Creating lists of Widgets and modify them using using the
     "configure" method.

The latter method is demonstrated in

    ftp://ftp.visi.com/users/grante/stuff/queens.py

In the queens.py case I'm changing the color and releif of a
label rather than the string, but I think you can see what's
goign on.  The grid of widgets is created in Board.__init__(),
and the widgets are changed in Board.placeQueen(), and
Board.removeQueen().
