IUP[0] has not been menthioned. IUP is wrapper for gtk+, motif and win32. Pros: * really simple api * native toolkit * c api, so other languages can easily write binding for it Cons: * controlls(widgets) are limited * cocoa(mac) is not supported {they suggest to use gtk instead} * documentation is spotty * nobody is using? (I believe no linux distros have it in repository) somebody here menthioned libui[1], it is exactlly the same philosophy [0]http://webserver2.tecgraf.puc-rio.br/iup/ http://webserver2.tecgraf.puc-rio.br/iup/ [1]https://github.com/andlabs/libui https://github.com/andlabs/libui
