gtkD window centering message up and no app on taskbar

[Johnson via Digitalmars-d-learn]

Also, could there be an easier way to import everything that is 
generally required?

I'm using an import script that does the work but I have to 
replace it upgrade time I upgrade gtkD(since I have to delete 
everything). I find that having a ton of imports is a big ugly.

What I use is, which was basically extracted from some gtkD 
example:
[It also lets use generate json for it a bit easier and use with 
easier. Probably could be enhanced but just something I through 
together]
