Dreamweaver is a worthless bloatware, no real web developers use a WYSIWIG.
Here is a list of options for you.
1) Learn PHP/HTML skills like these will make you more valuable as a person and allow you to understand the internet a bit better when you visit websites. When I see a nice website I automatically can pick out the CSS features a developer did and what type of design pattern they followed. (980gs, fluid width, and cluster fuck). If you do take this route I recommend either Notepad++ or Aptana Studio as your text editor, and Filezilla to upload the files onto your server.
2) Look into Drupal, Joomla is just way to big to be used for a small website. Drupal is similar to Wordpress in terms of adding content, but as you said Wordpress is for blogs. Drupal is meant for rapid website development it supports websites with content as opposed to blogs.
3) Use honorbuddy to bot you up some gold, sell it, and have me build you a custom CMS for your needs.
