"Tap Friendly" Widgets

I was curious is there were any more "tap friendly" widgets for JUCE as a 3rd party add-on possibly. I'm specifically looking for a "StackPanel" (http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/client/ui/StackPanel.html), or something to use as a mobile-size replacement for tabs.
