Display select Document Libraries on Page

I want to display on a page all document libraries with read access, shared access and secured. The best way to categorise these, I think, is to associate libraries with content types. So I'll have 3 content types which dictate permissions. (Permissions set manually). Now that the libraries have content type I need a way to display them on the page. So if its Content Type Read then I see a green icon, clicking on this will navigate to the library. If CT is Shared then I see an amber icon .. ect.

I've provided a high level idea but maybe theres some other way to tag the libries siginifying access levels.. even read the permissions directly..

Any ideas on how to achieve? I dont have CQWP (publishing is off) at my disposal so maybe front end / back end code ?
