It works for me, but takes a couple of seconds to digest all the gtk 
files. There is no completion before that finishes. I've tried it with a 
file looking like this:

module gtkAll;

public import gtk.AboutDialog;
public import gtk.AccelGroup;
...

The project built JSON file only covers the files actually in the 
project. You can create a full JSON file with the help of rdmd, e.g.

rdmd -X gtkd\gtkAll.d

That will likely fail due to object file generation or link errors, but 
should still build the JSON file.
