Sockets in GTK+?

[n3ck <n333ck gmail com>]

Hi every1!
Im was delphi (win) coder for a while but now i use linux as OS.
I really like to code so i choose GTK for build applications on linux.
I have been searching for some tutorial, text or articule about how
to build cliente/server apps using GTK but i could't find anything :(
Somebody has some clue, url or something that helps me with this?
thankz a lot.
Best  Regards n3ck
