[Wicket-user] Two things that I can't understand easily, just in the HelloWord application

[liigo]

Two things that I can't understand easily, just in the HelloWord  
application.
With the HelloWord demo application code following:

package wicket.examples.helloworld;
import wicket.markup.html.WebPage;
import wicket.markup.html.basic.Label;
public class HelloWorld extends WebPage
{
    public HelloWorld()
    {
        add(new Label("message", "Hello World!"));
    }
}

"add" what to where?  why "add" it?
why "new" a component? Does not the components EXSIST in the markup file?
Why not "attach" it?
again, I'm a newbie of Wicket!
Another question, Tapestry 4.0 plan to remove the prefix "I" of the Name  
of interfaces clsss such as IRequestCycle,IPage, (rename to  
RequestCycle,Page, and so on).
and there is a lot of discussions on why or not do this at  
tapestry-user@jakarta.apache.org  
(http://news.gmane.org/thread.php?group=gmane.comp.java.tapestry.user)
Maybe Wicket will do the same thing? Just before 1.0 released?
