Just go with wordpress.

joomla is another if your dying to use something else though

+1 for WordPress. I'm not generally good with technical stuff, but it didn't take me long to figure out WP. Plus, you can make it do anything.

Wordpress is the easiest and most customizable cms.

I cannot find a need to switch to something else to be honest.

Given that you're not familiar with HTML/CSS, I'd also have to recommend Wordpress. It's very easy to set up and administer. Publishing content is quite easy.

If you do go with WP, you may also want to check out WP SEO plugins like Thesis. I use it for all my WP-based sites - it makes the designing & SEO/meta-tag process a breeze!

Bloated content management systems like Joomla or Drupal are terrible for the end-user experience and not very developer friendly. Concrete5 is a new powerful CMS that is easy for developers and even easier for end-users. It works on a in-context editing model so you make changes as you're browsing your site. No more portal clones! If you're tired of long training sessions and tons of client support requests, try a demo of Concrete5 here: bit.ly/concrete5cms
