The idea is indeed to subclass grok.Container and add your own views.
You could use interfaces if you like, but you certainly don't have to
for a simple app. Stay away from zope.app.folder - I don't think it
contains anything you really need.
I have an example here that might be close to what you'd like:
Look at simplecms-0.2.tgz.
Concerning the ZMI, if you just override index and whatnot the ZMI
should be gone. You can go more sophisticated with layers too, but

containers are really simple compared to Plone folders.
I've been devising different approaches for interfacing with relational
databases (and other things) using URL paths (look at traject,
megrok.traject), but the "default" way I deal with things is container
too. megrok.rdb is a container centric approach to interfacing with
