That's a fairly broad description, isn't it? At least I have a hard time coming up with windowing API models that don't fundamentally work that way at the lower levels. (About the only exception think of is a text-based library that shipped with Microsoft BASIC 7.0, and that was mainly because the language didn't support any of the abstractions needed for callbacks.)
That's a fair point, I'll restate: the level of abstraction that developers were exposed to was 95% the same. Exposed message loops, window classes, window messages, unpacking window params, post and send message semantics, painting, single cooperative input queue (window app hanging would hang all apps), and other equivalences.
