Sectional CMS Plugin

Hi

I have been looking at themes such as the revolution theme where wordpress is used as a CMS. What I like is the ability to show a large article then below that a few snippets in different sections. Is there a way to do this (plugin) so all info is dynamic and so that the client can edit text in all the pages without touching any of the code.

Ideally for the front page I would like to in effect show one large piece of information and then be able to create other pages (which are styled to be small) which fit like modules below the top piece. I guess a bit like side bar widgets but for breaking up the main page with different information. I know you can do things like this with Joomla, but I find it too complicated.

Thanks
