I can't recommend a product a) because I know nothing about Windoze software and b) because I've always coded by hand (as OI assume you do).

However, whatever you choose, make sure that it can produce markup that is:

1. Valid
2. Accessible

(1) Is an inherent part of (2) and (2) is a legal requirement in some countries - but good business and moral sense everywhere. (Everyone should be able to use the site, including people using screen readers, people who navigate with keyboard alone, people who use no keyboard, people with mobile devices, etc.)

See this W3C resource for general information on web accessibility. If you are in the USA, you should also familiarise yourself with 'Section 508' - don't have a bookmark for that, but Google Is Your Friend.

As an alternative to running software on the local machine, how about using a CMS like Drupal, Mambo, etc.? For simple sites, WordPress can do a reasonable job even if it is primarily a blogging application.
