I'd suggest Atmel's AVR series, either ATtiny or ATmega, depending on the 
requirements, but I'd think a puny ATtiny13 will suffice. They're around 
1.50€ each and impressively well equipped (although only 5 I/O pins can 
be used, or 6 if you don't want to use the /RESET pin, which you probably 
wont - it's used for in-circuit serial programming).
Atmel provides an IDE with an assembler and a simulator, you can install 
a GCC variant for the microcontrollers too. 
I've built a simple music-box (out of an cheap MP3-player) with a motor 
for my baby-boy, with programmable run-time and motor-speed. All driven 
by an ATtiny13 and a C program. It's really enjoyable, so give it a try!
