Although apparently limited to more IO and controller jobs, the free Psoc Express seems pretty cool... Simple drag and drop gui interface, no code required at all. If you need a basic controller application (output dependant on some combination of input+logic), it almost doesn't seem to get much easier.
That said, I'm just starting out with this platform. I was a bit dissapointed to find no easy way to work with many of the internal analog blocks like filters with Express; I guess you need Psoc Designer for that stuff. Still, it is a very interesting platform with the combination of analog and digital blocks.
btw... if you seek, you may find. Astalavista.
