Here's how I did this using pygsear:
http://www.nongnu.org/pygsear/


# guess.py
import math
import random
import os

from pygsear.Game import Game
from pygsear.Widget import StationaryTextButton, Dialog_OK
from pygsear import conf


class Button(StationaryTextButton):
   def __init__(self, game, n):
       self.game = game
       self.num = n
       StationaryTextButton.__init__(self, game.window, text=str(n), 
callback=self.cb, border=0)

   def cb(self, ev):
       if self.num < self.game.choice:
           self.game.erase_to(self.num)
       elif self.num > self.game.choice:
           self.game.erase_from(self.num)
       else:
           self.game.victory()


class GuessingGame(Game):
   def initialize(self):
       numbers = 200
       self.numbers = numbers
       self.choice = random.randrange(numbers)

       self.buttons = {}

       nx = int(math.sqrt(numbers))
       dx = (conf.WINWIDTH - 100) / float(nx)
       x0 = 40

       ny = int(numbers / float(nx))
       dy = (conf.WINHEIGHT - 100) / float(nx)
       y0 = 20

       nr = numbers - (nx * ny)

       for y in range(ny):
           for x in range(nx):
               n = x + (nx * y) + 1

               b = Button(self, n)
               self.events.add(b.events)

               self.buttons[n] = b

               x1 = x0 + x * dx
               y1 = y0 + y * dy
               b.setPosition((x1, y1))
               b.draw()

   def erase_to(self, num):
       d = Dialog_OK(message="%s is too low" % num)
       d.modal()
       for n in range(1, num+1):
           try:
               b = self.buttons[n]
               b.clear()
               b.events.disable()
               del(self.buttons[n])
           except KeyError:
               pass

   def erase_from(self, num):
       d = Dialog_OK(message="%s is too high" % num)
       d.modal()
       for n in range(num, self.numbers+1):
           try:
               b = self.buttons[n]
               b.clear()
               b.events.disable()
               del(self.buttons[n])
           except KeyError:
               pass

   def victory(self):
       d = Dialog_OK(message="Yes!\nThe correct number was %s" % 
self.choice)
       d.modal()
       os._exit(0)


if __name__ == '__main__':
   g = GuessingGame()
   d = Dialog_OK(message="Guess the correct number")
   d.modal()
   g.mainloop()
#end guess.py

I am not sure if the Button really needs to know about the Game,
but I find that tends to happen pretty often. Maybe I could define
the callback in the Game, and pass that to the button...  I should
probably study up on MVC myself  :o)
