Answer 1

You can't just install a new libgtk package willy-nilly; you need to upgrade the packages that it depends on, at the same time (in this case, libglib, libcairo, and their respective dev packages).

(This question is more appropriate for Super User, and I've voted to migrate the question there.)

Answer 2

You probably want apt-get install libgtk2.0-dev=2.18.3-1, because most people really don't want to be in the business of manually managing package versions and dependencies.

But if that doesn't work, you'll need to manually look at the dependencies of libgtk2.0-dev (with apt-cache show libgtk2.0-dev) and download the matching versions of each package it depends on if they're not already installed (again, apt-cache show (dependency)).
