JJoodkokksokKKSk: Creation KIT, not club. Try reading the post next time.
Darvond: Or maybe Bethesda could have chosen named of better aclarity. Point is, no. There is no workshop for the stuff to connect to in the first place.
Creation kit and creation club are totally different things:
the creation
club is an online shop for some mods, which is not needed on gog, since the anniversary edition update installer is the complete creation club mods, without the now useless shop..
the creation
KIT is a toolkit used to create or modify mods, notably the creation kit is usefull to port oldrim mods to skyrim se/ae (only the esp, for meshes, textures and animations, you need the cathedral assets optimizer).
So no matter what, even on gog, the creation kit is needed for mod creators.
So no, it's not the same thing.
