You can do all those (sorting, filtering, etc) in Qt as well using the Model/View components. There is a bit of a learning curve to understand the "Qt way of doing MVC", but after that it works fine.

At work we use Qt5 with both C++ and Python (through PyQt) and I love it.

yep, Qt (Pyside) is very mature and very stable. In a professional, long term context, it's totally decisive.

Thanks! What I'd like to know more specifically is if there are some ready-made components already packing a lot of these functionalities without needing too much custom logic, or you need to roll out your own from low-level ones?

QTableView supports pretty much everything. Model proxies like QSortFilterProxyModel give sorting and filtering on models not supporting it natively (at a performance cost, i.e. keeping sorting columns in memory).

The model/view components scale to ~infty items, if the model is correctly implemented. They also support lazy loading.
