Ok, I've put it into module, linked in the module
pragma(lib, "user32.lib");
and
pragma(lib, "gdi32.lib");

all this works until I put

extern(Windows) ATOM RegisterClassExW(const WNDCLASSEXW *lpwcx);

on line 30, then I get as if this was a code not a new function 
import:

.\mod\myModule.d(30): Error: undefined identifier WNDCLASSEXW, 
did you mean struct WNDCLASSEXA?
