If you want a free, online, wysiwyg website creator, try Weebly.com
Can't get much simpler than that, and makes OK looking sites...
Personally I use Wordpress for a lot of sites. Easy, flexible, lots of nice themes, adsense optimized themes, lots of nice SEO plugins and stuff, and it's free.
I also use RapidWeaver but that's just for the Mac. Costs money, like $40 or so.
For my most important sites, the CMS thingies are no good. I never get it down exactly as I want it. Therefore I just make the site from scratch using a text editor. This way you get exactly what you want, but it requires knowledge of CSS and Html. Not much harder to learn that than to try and learn Joomla which I tried but it was daunting...
