using maxscript by object propties/parameter

I`m wrking on rigs and have to create spline panel for quick controll of
facial and bones but I would need to put some control for things I have no
access from reaction manager like hide/show objects etc. Normaly I would build
ui for maxscript panel but this should be "light" whole control must
come from spline panel. Is there any way to connect e.g object movement with
executing some commands in maxscript, like move object up = show objects ....
I can`t figure this out.
