On Windows DFL https://code.dlang.org/packages/dfl is great.And 
it is execellent with its GUI designer (Drag & drop components) 
Entice http://www.dprogramming.com/entice.php

dub fetch dfl and dub build dfl -a=x86_64 works smoothly ever 
since.

And interop with win32 api within DFL is as easy as if win32 api 
is integrated.
