A Book on pseudo-OOP for GTK+?

[Kang Jeong-Hee <Keizi mail co kr>]

Please show me the way to POOP for the inside of GTK+, Master.

I have no idea about OOP or C++, and not good at C.
Almost that I learned about C and GTK+ is ones by trial.

I'm thinking about
  a) C++: The Core Language, by Oreily
  b) Microsoft Visual C++ Object-Oriented Programming

which's better? and which's fit to c)?

I want to make my own widget. and to understand bonobo more easily.
without OOP, POOP is hard to understand. let me study OOP.

thanks.
