you can write arbitrary text to arbitrary positions
in the coordinate system of the molecule using the
graphics text command.

if you want to update it dynamically, you have to
keep track of the graphics id's that are the return
value of each graphics command, store them away in
a globally accessible location (or using a namespace),
and then put a trace on the vmd_frame variable for
the molecule, so that you can selectively delete and
redraw those graphics commands.

cheers,
