Basically the two different strategies you have is to either set the visibility of components (or override isVisible) appropriately, or build up the hierarchy dynamically. As an example of the latter, you could have a are in your page you call top bar. When you construct the page, you decide whether to add the top bar with the login panel, or the top bar without (e.g. to show the panel that displays the logged in user's name). The templates example in Wicket examples shows something similar.
