You need to set the command parameter of the Button widget to a Python
function and make the Python function call an external program via
os.system()

Why not just give her a login using her preferred windowmanager? Thats
what multi user operating systems are for - each user gets the
environment they prefer!

The command parameter is your friend.

Check my GUI topic on my tutorial which shows very simple use
of Buttons and the command parameter.
