If that doesn't work then forget zenity and lets get gksudo/gksu working. My problem is I am a beginner. I am not confident that I would get all the bits and pieces (libraries) required to make gksudo/gksu work smoothly no matter how they were launched or used in a script in Fedora.
The default solution used in Fedora is consolehelper. Might consider look at packages like system-config* tools and the man pages if you want to know more details.
