Manage a simple list of items in frontend as a registered user

Hello!
Me and my friends like to read books, and I thought to create a simple wordpress theme for us, so each of us could post his own list of read books.

Each person would have a registered user, so they could manage the list created.
Not all of them knows to use wordpress, so i’m thinking to a simple method, like a button in frontend for adding a new list.
After the list is created, the ability to add or remove list items in frontend, or adding rating and tags for each list item.

I’m not asking the code, just some guidelines to know from where to start, or if is possible.
I’m learning to create wordpress themes, so this would be a good opportunity to gain more experience.

If there’s already a plugin who does that, i’d love to hear about it.

Thanks in advance.
