You may want to look at:
http://cglib.sourceforge.net/apidocs/net/sf/cglib/reflect/MethodDelegate.html

It can create an object that implements an interface but delegates the
implementation to a virtual or static method (with matching signature) of
your choice. Essentially it is a implementation of C# delegates for Java.
