No. AFAIK, there is only a Windows Explorer plug-in for showing the preview. I don't think it would be a big deal for a Mac QuickView plug-in for GDL objects to be produced (and Snow Leopard would generate an icon from the view - which would just be the preview image), but there isn't one that I know of.
