It's just some standard GUI type stuff that comes standard with almost all versions of Python. The Tools archive (from Alf's blog) has a GUI front-end for MobiUnpack that will work for pretty much any O.S. (that has python installed, of course). It allows you to choose the files and output directories with standard file dialogs and familiar buttons and such. You have to
install python, but none of the scripts really require you to get down and dirty with command-line stuff if you don't want to... while still allowing those who actually prefer to get down and dirty, to do so.
