xCode is a program that organizes your source files and a GUI for the GCC compiler (it's called an IDE, Integrated Development Environment)
Objecticve-C is an OOP language that is the mechanical means by which frameworks are used - it's the glue.
Cocoa is the set of frameworks that are your pre-made resources for doing stuff.
I suppose you could re-write your favorite procedural C program with Obj-C, using all the same frameworks and functions as before, but just organizing it in an OOP pattern.
