Is Tkinter compatible with GNOME?

[Mulac]

Is Tkinter also compatible wih GNOME?

I wrote a program in python that displays 2 buttons for starting and stopping the
execution of a program.
I used Tkinter for the gui.
I want the program to run as a daemon when linux is booted.
I want the buttons to be displayed at the presession login screen.
I am using Fedora core 4 with GNOME

I cannot seem to get the buttons to display at the presession screen.
I figure it is either that the init script I wrote to make the python program a daemon
isnt working right OR Tkinter cant do the job.

Any thoughts?
