What are the real GUI toolkits for D?

[nbro via Digitalmars-d]

Except for GtkD and DWT, D does not seem to be supported by a 
really nice GUI toolkit. Anyway, a serious programming language 
nowadays should have a lot more support in that area. I have not 
tried GtkD yet, but it seems the most promising. Many projects 
have started to create a GUI toolkit (or wrapper), but now they 
are abandoned. Are there any plans to really support the 
development of standard GUI toolkit?
