I would actually suggest going to the bookstore and sitting down and reading a basic guide to HTML and CSS. If you won't be doing anything really complicated, those two things are all you should really need. However, there are HTML-help sites all over the internet (I've given you two I frequently use down below).
Once you get the basics of both down, I would suggest you "design" your site, using pencil / pen and paper. Draw out a few layouts that you want to use. Then, see if you can't roughly guesstimate what kind of html you would use to design it.
I'm not sure if these will be applicable, since I use them more for the coding side of web design (I code from scratch), but they still might be of some help to you. W3Schools
is pretty useful as far as code and such goes - I've never used any of the tutorials they have there, though such tutorials do exist. WWW Consortium
is also useful.
