I have to agree with Steve on this one. It sounds like you want to
design the entire circuit from scratch . 
I usually don't recommend this ..but in your case you should go to
radio-shack and look into getting a basic-stamp learning kit. The
basic stamp is a microcontroller that should suit your purposes, and
there are a LOT of forums and groups out there to provide you with
circuit design help and programming support. 
Also check out the Parallex ( spelling ? ) web site .
Do a google search on "BASIC STAMP"  and "BS2P" .
Hope that helps.
