Native GUI development for MacOS

[Neodim]

Thanks for reply, I've tried wxnim but it does not work out of repository: it 
returns a dozen of various errors upon compilation of its examples. Same time 
wxWidgets itself was compiled fine at one click. I guess it is due to non 
maintainable code which is not up to date to current NIM and wxWidgets versions 
(like ca 6 year old...).Actually its just amazing, why so obvious task like UI 
for mac has no simple solution... nobody need it? Anyway still looking for a 
working solution...
