As jcdenton said, the pregame editor is needed to create database addons.
Regarding the 2 packs you mentioned, as far as I know, Timo retired from making databases last year after some not so cool criticism he received on SI forums. And I'm not sure if qwert is making his own databases, or mostly including other people's files in his packs.
I'd personally wait for the works of DaveTheEditor and Weiry. They've had the most realistic and complete league packs for FM21. Both packs are featured on my list of handpicked addons that make FM21 more realistic.
