If you're looking for a content management solution that's easy, WordPress is the way to go. 

Usually there's a tradeoff between ease of use and flexibility, but not with WordPress. It's the most user friendly content management software, yet you can customize it and add plugins to do pretty much anything.  There are over ten thousand plugins to handle the most creative wish list for a web site.  If you can imagine it, someone's built a plugin to do it.
