Good for anyone looking for a Python GUI for use on Windows 64 bit here!
1) Install python.org with 64-bit python. If you already have python installed on your system, you do not need to worry about that.

2) Add additional parameters / environment variables to your PATH; C: \ python27
3) Then download everything into one installer from GTK +
