Best GUI library and GUI designer?

[December Flower]

Hi there.
Sorry for my poor English first.

I just started D language and looking for GUI library and 
designer.
I found some.

GUI libraries from D wiki and
Designers are Entice or Bud.
but it seems that there's no further development.

I found few threads and they are all stories of 2 or 3 years ago.

So I'm wondering if you can recommend some GUI library and 
designers to start with. For the text editor, I'm currently using 
gVim.

Best regards.
