Project Suggestions for building a QR Code based private library

I'm quite new to programming and a huge fan of learning by doing as I've done in other fields of expertise as well, so I wanted to start out with a not too complex project.

Project description: I've got plenty of books at home (easily more than 100) and I want to implement a web solution which should represent my "own little library". Additionally I thought about QR Code stickers which I'd put into every book for fetching information about it (in which shelf it lays, my review about it, author, etc).

Could anybody give me some suggestions to the architecture? I thought obviously about using HTML, CSS because it should be a web solution and maybe a python backend (I don't really care about languages). Maybe I'll have to build an API for getting the book data form the QR code? Any database suggestions?
