Ellington is based on Django (http://www.djangoproject.com), and seems to be well suited for creating "CMS-y" type applications. I've had a little play with it myself, and like what I've seen so far. If you're end up deciding to 'roll your own', I'd definately take a look at Django over PHP as a starting point.
