The question does not have to be directly related to Linux and any language is fair game.

Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Do you think I should get the Display object of the 'VLC media player' window and start drawing on it? Do I need special permissions to do that?
I also tried the following (Clutter and X11 together):
clutter_init (&argc, &argv);
ClutterActor* stage = clutter_stage_new();
// 'p' is the xid of 'VLC media player' main window
// I found 'p' using "xwininfo -root -tree" command
clutter_container_add_actor ((stage, rectangle);
// rectangle is just an object (a ClutterActor, more precisely).
With this, I've got the following run-time error [where 0x4800037 is the xid of VLC's window]:
ClutterGLX-CRITICAL **: Unable to make the stage window 0x4800037 the current GLX drawable
Clutter library is using OpenGL for rendering. Could this be a problem?
Anyway, using Clutter is not actually a 'must'. I haven't try with GTK yet.
Example of what I would like to do: when I watch a video (full screen), I sometimes get notifications from Network Manager (it gives me information regarding the Internet connection). I want to do something similar, I want to draw on the top of the 'fullscreen'.
Is the X11 example from Wikipedia (link above) a good start to do that? Any advice is welcome.
Thank you a lot for your help, kalleanka!
The example works fine
The only problem is that an application running in full screen mode covers the little window. Well, that is not actually a problem, I think I was a little stubborn about creating such a window. I realize now that it isn't really possible. That is, when an application goes into full screen mode, it says: "The screen is only mine now, so... stay away of it!"
