I learned with just Notepad, and I think that every aspiring webmaster should first start with their head, notepad, and maybe the occasional w3c validation. That way, your skills are your own and you have a deep understanding of the code as opposed to have something like Dreamweaver do it for you.
Edit: Sorry bout the double post. Apparently my Internet decided to die when I was posting this, so Firefox sent two posts instead of one.
