 I think for the release 1.0, a thin FFI layer should suffice.

This is a good idea, but the way I see things is that, initially we should 
just endeavor to provide raw ffi bindings first for clisp. And then when 
that is done, some of us should work on porting to other implementations, 
while a small group should work on providing the object system, a top
layer which binds to the different implementations and thus provide an 
implementation independent way of creating GUI. I agree with Joerg"s
layered approach.

 For the ffi layer implementation, we should have a naming convention such 
that the function names are same(or close to) the wxWidgets name, only 
thing is that they might have the implementation "clisp" as the package name.

The lisp style of naming should be used for the top layer.
