This is my version of your script, its a gui except it only for windows. I cant get it to run at all in wine. Version 1.1.28 http://www.mediafire.com/?d326qgckb58k4e1
I just recovered the things i didnt mean to delete deleted a long time ago
I made another version of this script, it's faster because it uses glob.glob, but has no GUI. This script automatically renames files with less than 10 chars by adding some "0", and prints a warning for files with more than 10 chars. IMPORTANT: before use, open with a text editor and change the absolute path to Powder Toy! Tested under Linux w/ Python 2.6 but should work on every OS w/ Python 2.x.
