I wouldn't even rule out a basic stamp. I had a lot of fun when I was programming those.

Depends on your programming experience. PICs, the Picaxe, Arduino and others are all capable of the tasks you describe. So it comes down to what you know (and what you want to learn).

Most PICs require assembly, as jklug80 points out. I hear great things about Arduino if you know C or other higher level programming languages. If you are a beginning/middling programmer (like me), Picaxe is a great place to get started, since it has a Basic-like language.

All: We get this question so much. We should collect some good replies and include it in a FAQ.

I'd recommend an Arduino. It's pretty much as easy to program but WAY more powerful and flexible. It's also cheaper and has a very nice community with lots of helpful people. It also comes with a free compiler.
PICAXE is the way to go for beginners. IIRC, it comes with a free code editor.
hmm thanks any suggestions on the software i should use ?
Picaxe has a bootloader that allows you to use basic. A lot of PICs require assembly. If you're new go with PICAXE.
