Hi,
I can make a gui interface and convert it to an windows application by converting your script in a .exe.
And i can give you, and explain how to turn your script with the given file, so you ll be able to modify it and convert it to an application yourself.
If by converting it to an application you mean converting it to a linux debian/ubuntu package, and have it in the applications menu, i can do it too.
About me, i'm a python expert, speciallized in python mobile development and python packaging.
See my PM
