sorry, i haven't finished reading the whole of your reply yet, but i
thought i'd clear this up real quick. GUtopIa is doing a sort of Lazy
Evaluation. I've done this in preperation for the fact that other
toolkits require predefined parent widgets, unlike GUtopIa's API and
GTKs. this isn't fully implemented yet, but this lazy eval makes it
possible. anyhow the create() method is called from the Application
class:

    def start(&kickstart)
      puts "starting application..."
      Platform.initialize
      @views.each do |view|
        view.components.sort.each do |component|
          component.create
        end
      end
      instance_eval(&kickstart)
      @views.each do |view|
        Platform.start
      end
    end
