Anticipating the day when multi-touch interfaces become more pervasive, are there libraries in Java that can be used for developing touch applications? I'm looking for interfaces similar to MouseListener / MouseMotionListener / MouseWheelListener.

The MT4j project has everything you need to develop multitouch applications in java. All the well known multitouch gestures are already built in and can be accessed as simple as listening to mouse events (for example: component.addGestureListener(..)). It also features a hardware accelerated scene graph, similar to JavaFX. You can even simulate multitouch input by connecting one ore more mice to your machine. Check it out at http://www.mt4j.org
