yes, but if YuiButton extends Button, it can't share code with YuiMenu.
meaning, i cant create an AbstractYuiComponent

i don't understand what you mean by concrete delegates.
but concerning the pattern, i think it will be cool to be able to switch
widgets easily. say i have a ComponentFactory that returns Component classes,
but it constructs them around an implementation based on some configuration. So
a page just uses a Button, with a YuiButton, or a HtmlButton. The page always
looks the same (and the YuiComponent hierarchy can reuse code through
inheritance)
