Maybe this can serve as an overview of where is everything:

For generic GTK apps (not necessarily targeted at GNOME): https://www.gtk.org/docs/apis/

For GTK apps that integrate well with GNOME: https://developer.gnome.org/documentation/introduction/components.html

Also, for new projects, if you would like your app to adapt well to different screens, like modern web apps do, maybe take a look at libhandy (https://gnome.pages.gitlab.gnome.org/libhandy/) and libadwaita (https://gnome.pages.gitlab.gnome.org/libadwaita/doc/). The latter, if I understand correctly will replace the former.

Also, note that Glade (https://glade.gnome.org/) only supports GTK 3, and there doesn't seem to be any plans to support GTK 4, so people seem to be writing GUIs by hand in GTK 4 projects.
