There been very few discussions about GUI. Mostly that immediate mode API is a way to go. It will give you the most flexibility.
Here's a video from Casey on immediate mode GUI: http://mollyrocket.com/861
And Here are some nice libraries following this concept:
dear imgui: https://github.com/ocornut/imgui
nuklear: https://github.com/vurtun/nuklear
Papaya and Milton projects use dear imgui library.
Who needs search when you have mmozeiko? Thanks a bunch for the pointers, those look like much better starting points for my work than I'd ever dared hope to find :-)
