we have such an internal theme, which we have used for some stores.
It's not perfect, but not bad as a start.
The theme can be downloaded here.
The folder in the zip file must be copied to the themes folder on the server and the theme must be changed in the backend.
We will provide a more fancy CMS theme soon (more likely next year).
