A GUI library to begin with

[Mr. Anonymous]

Hello,

I want to start playing with D, and I'm looking at a GUI library to 
begin with.
 From what I see here:
http://www.prowiki.org/wiki4d/wiki.cgi?GuiLibraries
I have four choices:
GtkD, DWT, DFL, DGui.

Has anyone tried these? Any suggestions?
What is the status of DWT? What's the difference between DFL and DGui? 
Why does GTK suck (I read that a couple of times).

Thanks.
