I changed test.d to be the same code as in the 
HelloWorld.d(https://github.com/gtkd-developers/GtkD/blob/master/demos/gtk/HelloWorld.d)example that is provided by the GtkD github.  Adding the comment to the top of the file and removing the .json doesn't change what happens.  Dub runs the program, but an executable file doesn't pop up next to it.  Running ./test in the terminal returns a no file or directory error.  Another thing. Apparently dub run is the default command, but running dub run test.d gives an error that the package test could not be found.  Same with dub build.  Running dub test.d still works just fine, for some reason.
