Resources for Rolling Your Own Windowing System?

WalterGR asks: "There are plenty of resources available for writing operating systems, e.g. Tanenbaum's Modern Operating Systems, the Dinosaur Book, and countless web sites. For those of us who aren't interested in low-level issues, and prefer focusing on human-computer interaction, what resources are available for designing windowing systems (a la X Window)? Issues like the object hierarchy, event management, modularity, redefining behavior at runtime (e.g. for skins) etc. Any suggestions?"

Re:OWL, MFC, K, etc.

Also Swing (in java) and Win32 from MSFT for what NOT to do, heh.. Actually MFC fits there too ('we determined simple inheritance was too straightforward and our implementation was inefficient so you can run these gawdawful preprocessor macros to interface with the message-passing system...)
