Hmm, but you are using GtkD in your example... It looks like you 
compiled the wrong code.
What you actually want is GtkD from 
https://github.com/gtkd-developers/GtkD or installed from the 
Debian repositories (in case you want to use LDC) via `sudo apt 
install libgtkd-3-dev`

If you want to use GtkD and achieve a quick result, you might 
want to use the Dub package manager.
GtkD also has a few demo applications that show you how to use it 
with dub, take a look at
https://github.com/gtkd-developers/GtkD/tree/master/demos/gtk

tkd is a project different from GtkD (which your example above is 
using). For "modern" UI that integrates well with GNOME, you will 
highly likely want to use GtkD. Tcl/Tk is of course an option as 
well, but the D bindings look less complete and well maintained.
In case you want to use Tk, you will need to change your code to 
actually use it, instead of GTK+ though ;-)

I can't help with Tk, but for GTK+ a quick Google search found 
https://sites.google.com/site/gtkdtutorial/ - this tutorial is 
rather old, but it might be useful as a reference.

This experience report by Gerald Nunn might also be an 
interesting read for you:
