Global hotkey with GTK based application under Windows

[ANtlord]

Hello! I implement a GTK-D based application for Windows and 
Linux. In case of Linux there isn't any problem, I use binding[1] 
for libkeybinder. In case of Windows I can't find convinient way 
to implement global shortcuts. There is a way to get it done is 
use of WinAPI but it's not convinient by a couple of things.

WinAPI provides RegisterHotKey method[2] but I have no idea how 
to get HWND using GTK-D. If I get it done I get a problem to 
handle it. Design of WinAPI means handling of hotkey in a loop 
like so[3]. I could get the thing done using tick callback[4] but 
I use the callback for another stuff, and I don't know whether 
GTK-D supports multiple tick callbacks, I can't get it at least.

If anyone has an idea, please tell me because I ran out. Thanks 
in advance!
