Hi Jamey,

First off, many people will agree when I say ditch Tkinter, and switch to
wxPython. Never the less...

Not knowing a lot of Tkinter I would guess you can initialize these buttons
to be in the "greyed out" state, and create an event on the two input
fields that checks for any data input. Make the event call some validation
function if you need it, and change the state of the button to "non-greyed
out" if all is well!
