The Composer module in Netscape or Mozilla is not a bad place to start building a web page. It has the distinct advantage of being free as well. If you are planning on using .Mac to host your site, they have a decent online web site builder that integrates smoothly with your .Mac account and is very automatic but produces decent results. Most ISPs that provide site hosting with their accounts have similar online site builder tools. Like Composer they are a no cost feature of the service.
If you plan to get semi-serious about web site building you need to spend some time at your local library or money at your local bookstore and read up on the technologies and techniques. O'Reilly Press and Peachpit Press both have good introductory books available.
