Turn Python command line programs into a full GUI application
... to walk through building a graphical interface to one of my favorite tools of all time: FFMPEG. These steps apply to anything, though! You could swap out FFMPEG for a .jar you've written, or an arbitrary windows .exe, an OSX .app bundle, or anything on linux that's executable! In short, it will transform a "scary" terminal command line into an easy to use desktop application that you could hand over to users.
