Stewart Watkiss, over at PenguinTutor.com has written some code in Python using the Tkinter library that produces a GUI for controlling NeoPixels with the MyPiFi NeoPixel controller board. The GUI has nice big buttons (so it’s good for touchscreen set-ups) and has plenty of options for standard sequences. It’s a work-in-progress and you can find out more and download his code over on his blog post.
