Transforms tkinter, Qt, Remi, WxPython into portable people-friendly Pythonic interfaces, especially if you primarily do CLI tools. Tries to make it easy to build GUIs for applications, because ordinarily the process sucks. Supports several toolkits, including QT, WxPython, and Remi (if you want to turn something into a webapp); you can switch between those toolkits with a single line. No callback functions, that's all handled for you. Has a built-in debugger.
