Taking it further a GUI designer shouldn't need to code but have good tools
for the job.
I think it would be nice if a designer would do a drawning, comparable to
what you do in CAD, specifying areas, relations and max and min sizes of
areas. ie width A= 200 +- 100. Then the whole layout could be tested and
then generated into executable code, and as much as possible precalculated
at generation.

Also the subareas could just be named areas or id's in the tool, so that
someone who implements FancyHelloWorld (later) could just say that
FancyHelloWorld should fill the FancyHelloWorld area. Separating layout from
implementation completly, as opposed to what is common now where the
implementor is often forced to implement the layout sketched by some layout
expert.

These are just personal opinions which I think doesn't seem to be that
different from LP.


I also recommend checking out http://www.jaxxframework.org which is really
cool when it comes to doing GUI apps under java. It uses many ideas from
HTML and even has quite advanced CSS handling. It touches on other ideas as
well, messaging (bean bindings) and so on.
http://www.jaxxframework.org/wiki/Examples/Calculator.jaxx shows good
example of separation between code and layout (although layout depends on
engine in this case).
