Thanks Jacob for the response but that did not work :-(  Below is 
what I get when I compile your hello world example above.


C:\Users\<myusername>\Documents\My 
Projects\Programming\DStuff\dwthelloworld>rdmd hello.d 
-IC:\GITClones\dwt
hello.d(3): Error: module Display is in file 
'org\eclipse\swt\widgets\Display.d'
  which cannot be read
import path[0] = .
import path[1] = C:\D\dmd2\windows\bin\..\..\src\phobos
import path[2] = C:\D\dmd2\windows\bin\..\..\src\druntime\import
Failed: "dmd" "-v" "-o-" "hello.d" "-I."
