I guess this would take longer when creating all widgets as more jni
calls are required. 
Would the reference be created using (*env)->NewGlobalRef so that the GC
doesn't free it?
If so, how will this reference be removed to allow the Java object to be
freed?
If not, then what will happen if the user does not keep a reference to
the Java object

Constructors would still be used when constructing a new widget.
Factory methods would be used when accessing an existing object (or at
least existing in the native sense). 
Why is this a problem? IMHO, it makes more sense than having everything
done in constructors.
