How to create a system using Django so that a naive user can edit the content of the Django website without using HTML code?

I have created a personal website for someone using Django (however it wasn't required since website is very simple, but it was their demand!). Now they want that they can edit the content of pages without editing HTML. They now want me to use Django-CMS, I again disagree as I don't think it is required (?) . What should I do to create a system so they can edit the webpage without messing with templates and HTML?

The webpages contains few listings, say of 'Books', 'Recent Visits'... etc. I was thinking to create a model for each of them, and let them edit the database using admin, which will then be used by Django to create a dynamic page for their site.

Do you think CMS would be a better choice (but then they don't really need me to do anything, they can do it by themselves!) ?

I perhaps didn't put my problem properly, but if anyone can understand it, then please give me your suggestions. I can provide more details if anyone wants.
