label = gtk.Label('Choose a program to run as %s' % os.getenv('USERNAME'))



On my system (FreeBSD) there is a USER env variable, but no USERNAME
Make sure you do su - and not just su
Are you allowing other users to connect to your x-server (xhost +)
Be very careful any time you run things as root (especially running
  things automatically from a script)
