Use Notepad. And by that, I mean, leard how to do straight HTML first. It's not that hard. Just go to Google, and type in HTML Tutorials.
Frontpage is VERY EASY to create web pages. But it's HTML is sooooooooo bad, and it's mostly IE proprietary HTML. Although, I don't think it's bad tho for making changes to existing pages. Dreamweaver is a real professionals tool. It can do a lot, and creates nice clean HTML.
So, to review:
Learn HTML
Don't use FrontPage
Use Dreamweaver, but it's expensive. (If you are in school, you might get this for a discount.)
