well, after re-reading my mail, I think I have left
some holes.

My question is: can the FCL acommodate GUI components ?

I think, at least, is worth trying.

I don't know how it should be organized, but if could
be done, it may be a great thing.

how 'bout:

fcl/
   linux/
   win32
   inc/          (the more code here, the better, of course)
   ...
   gui/
       gtk/
       win32/
       qt/
       ...

Of course, I'm saying that fcl/gui/win32 must be filled
by someone interested, not for anybody else.
The lazarus team (and eventually me, but I'm at the learning
stage) can work in the fcl/gui/gtk.
When someone ask: 'there is a Lazarus for qt ?' one can
say: 'yes, implement all the remaining parts in fcl/gui/qt
and you should be able to make a Lazarus for qt'

-O_O-  Keep working at it... you will either succeed, or become an
       expert.
