I don't think this will be possible.  As you say 'GUI elements' are not
64 bit ready.  More precisely, the only Apple-provided frameworks that
come in 64 bit varieties are System.framework and Accelerate.framework. 
VTK uses all kinds of others like Carbon, Cocoa, OpenGL, etc., etc.,
none of which are 64 bit capable.

So unfortunately, any code using vtk will be limited to max 4 GB of RAM,
probably more like 2.5-3 really, because of memory used by apple
libraries and fragmentation, etc.

Maybe OS 10.5 will have more 64 bit libraries.
