Re: GUI programming

depending on what you want, there are wrappers for 
[GTK2](https://github.com/nim-lang/gtk2) 
[GTK3](https://github.com/StefanSalewski/nim-gtk3) , and 
[AntTweakBar](https://github.com/krux02/nimAntTweakBar). The last one is just 
meant to be used as an overlay for game development and therefore supports 
widgets to manipulate vectors and quaternions, but offers little when you want 
to control how it looks.
