Using gtk+ in Xcode

[Hind Noor <hind noor yandex com>]

Hello,

I have 2 questions:

  1- Can  gtk+ be used inside Xcode? I like to write, compile, link, and run my project via Xcode NOT via the 
command line terminal.

  2- I installed gtk+ via Homebrew and it downloaded and installed all the required dependencies:

  Libraries directory for gtk+ and glib etc .. : /usr/local/lib/
  headers directory for gtk+: /usr/local/include/

How can i compile sample.c file under Mac OSX? what should i write in the terminal?

Thank you,
