If you are looking for a CMS, there are plenty of good CMSs out there.
The recommended ones are
PostNuke,
Joomla!, or if you want a "community look and feel" site, use
drupal.
Using a CMS is usually easy, and you at least have less worry about the security and stuff because all of them have been taken care of by the developer although new vulnerabilities might be discovered from time to time.
Creating new pages is as easy as clicking links and buttons.
They have themes you can choose from, or you want to make a small changes, you can change on the CSS with a little effort (like googling for a tutorial about a problem).
Basically all you need is a database and a server to house your files
This is just a suggestion if you want a fast and easy solution without having to know about PHP or other technical things.
