Can I install gtk on xcode?

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 fram开发者_如何学Goeworks in xcode though and I don't know how to install the GTK library/framework so I can start using it when I code.

You can find a popular GTK framework that works with Xcode GTK-OSX, at http://gtk-osx.sourceforge.net/
