I am making programs that solve and show work for math problems. I would like to add a GUI, and I think wxPython will be best. If I use wxPython for the GUI, will the end user need wxPython on their computer in order to use the program with the GUI? If not, what would should I use? 
These apps will be used on mostly Windows, but I would also like them to work on Macs and Linux. I'm not for sure if any Python GUI elements will work on Android through SL4A, but if you know any, that would be appreciated.
Also, I know Tkinter is bundled with Python, but is it a dying technique, as I have read?
Thanks!
