D "Swing"

[Chris]

Here is an article about difficulties in cross-platform GUI 
development (nothing new, really).

QtD doesn't need GCD anymore, apparently. I remember there were 
several fussy requirements for QtD a year or so ago that were 
rather off-putting.

Another GUI toolkit I have come across is this one:

http://www.tecgraf.puc-rio.br/iup/

It sounds very interesting and is based on ANSI C and / or Lua. 
If D bindings aren't too hard to implement it might be of 
interest to the D community.

It runs on OS X too using X11, but maybe the GTKD add on for Mac 
has solved this issue already:
