You can't.  Guile-gtk currently does not support much of Gdk.

How would you like to access this information.  There are at least two
general possibilities, and I'm not sure which one to provide.

- A ton of accessor function, so that you can do

    (case (gdk-event-type ev)
      ((motion-notify)
       (pk 'x (gdk-event-x ev) 'y (gdk-event-y ev))))

- Or a single conversion function that turns a GdkEvent into a
  association list

    (pk 'ev (gdk-event->alist ev))
    => ((type . motion-notify) (x . 12.0) (y . 13.0) ...)

Probably best to implement both.
