Yes, in a sense.  When you instantiate any VPython renderable object,
any extra parameters you provide will be automatically added as
attributes of whatever you are creating.  So:

>>> x = sphere( name='texte')
>>> print x.name
'texte'

See also the display.getclick(), display.getevent() functions.  These
return a reference to the nearest (closest to the screen) VPython object
that was clicked (if any was below the mouse cursor).  You can then have
a label associated with each sphere, and control it's visibility when
you process the event.  If you wanted to always move the label and
sphere together around the screen, you can easily wrap them together in
a common frame.
