Replace the above line to

button = Button(root, text="Click Me")
print "Button() returns", button
grid = button.grid(column=4, row=10)
print ".grid() returns", grid
self.click2 = button

and be enlighted. Then remove the print statements.

If one step doesn't work try to replace it with smaller steps and add print 
statements to find the part that doesn't do what you expected.
