FrontPage is easy, but isn't lacking in details and functions. There's also a lot of "stuff" out there for it. I wouldn't bother with any version lower than FrontPage 2000. Gets complicated on the older versions.
Ditto on the FrontPage vote...been using it for a short while now, so easy...the "true" programmers will laugh because it is a WYSIWYG program as NDC mentioned, they say the code is bloated and there's way too much of it.

There are other options, however they cost money. Such as Macromedia Dreamweaver and Adobe GoLive!
I personally use Dreamweaver, however, I got a good student discount on it.
Well if you want the best I'd say Dreamweaver, however its not full of premade templates and such. I think you'd have better luck with FrontPage if you wanted something simple. Dreamweaver has more power, but the learning curve Id say is slightly higher.
