Just saw an interesting post on EndGadget.com:

Basically it's a GUI program that allows you to put together an app without needing to directly write code. Looks interesting, although it's not quite clear how powerful it can be. I haven't tried it yet, but the video makes it seem quite accessible for those who otherwise lack the requisite technical skills to write even a basic app.
