You can use Glade (https://glade.gnome.org/) to drag and drop 
your GUI and then import it to a GtkD project (https://gtkd.org/).

There used to be a GUI designer for D named Entice Designer, but 
it is very old (from D1 times) and not supported to my knowledge.

Alternatively, you can make your GUI in another language (e.g. 
Java with JavaFX) and call the D functions from there, although 
it won't be a very convenient option.
