Advice in creating a Book Organizer App

Hello all,

I want to develop a Book Organizer application, similar to Bibshelf if its possible.
I wish to know what do you think is better for storing/displaying book lists, if a QTableWidget or a QTreeWidget.
I wish to store in some kind of table or list, the book's Author, book's Name, Category, and Rating. I wish to add and delete books anytime I want, and display the list everytime I run the app, just like Bibshelf.
I wish to sort the books by Author or Name too.

Do you have any advice you could give me, about clever ways to write this app?

Thank you very much!
