Nvu is a good choice for beginners: it's standalone and it has lots of easy-to-use features that aren't included with the real Mozilla/Netscape Composer.
Macromedia Dreamweaver is a very powerful Web IDE, that can take a bit of learning to master completely. Once you know what you're doing, though, you can use it to write all sorts of Web languages in addition to HTML, like CSS, JavaScript, ASP, PHP, and ColdFusion.
Microsoft's Visual Web Developer 2005 is a good choice for ASP and ASP.NET Web developers as well as plain HTML developers. You need some prior knowledge of whatever language you're going to design in to use it, but that aside it's flexible and free (for now, at least: when they make you pay for it in a year, it will be $50). Visual Web Developer allows you to create (X)HTML, CSS, JavaScript, and ASP.NET applications. You can use it for other XML-based formats as well.
It sounds like for all intents and purposes, your best bet would be Nvu. If you ever do learn how to code HTML, then I'd definitely say to trade up to Visual Web Developer.
