Hey there!
I've been doing PHP for a long time now and I'd like to make some desktop applications on my Mac. I've never used C before but I installed xcode and I could do some basic things with some terminal apps.
I'd like to make an application with a GUI. I don't know how to add libraries or frameworks in xcode though and I don't know how to install the GTK library/framework so I can start using it when I code.
