Help me on GTK+
 

Can any body provide e-books to program in GTK+, Is Qt is better than GTK+ to build GUI apps?

There is no better. They're different.

http://library.gnome.org/devel/gtk-tutorial/stable/

Not ebooks, but a pretty good place to start.

Google some by yourself too, it doesn't hurt.
