It's possible, yes, but I don't think it's easy.  The trick is coming up
with a trigger action that's easy to recognize.  The pen stroke is a
single PalmOS event (well, there's a PenDown, some PenMoves and a PenUp,
but the PenUp tells you everything you need to know).  Off the top of my
head the only analogous action on the Treo would be remapping a key (say
the calculator key, or something else you don't use).  Combinations of
keystrokes are tricky to work with because PalmOS uses a stream of
character events and Hacks can't easily have persistent state.  Note
that it's easy to remap the calc key in the prefs panel, but that
won't do what you want -- that would switch to an app, but you don't
want the app-switching overhead here.  

In short, you'll have to delve into PalmOS aracana to do this.  I can
give you an outline of what it would take to implement this if you can
tell me what sort of trigger action you'd like to have.
