It's not hard, but it certainly is a lot easier to use an hardware USART.
Also because most of them have a 3 byte buffer.

I'd recommend the 16F688. It is small (14-pin), modern (fits in the demo
board of the PicKit 2), and has lots of space to work with. Of course, you
might want to look at the 18F series as well, as these tend to be
friendlier.
