There is plenty of  material on-line. You can  go the rc_graphic route,  or
work directly with the widget sets. I'd recommend the latter if you want to
pick up an understanding of X-windows (and in general GUI programming) that
is not specific to Pop-11. But rc_graphic (see teach rc_graphic) is  faster
to get to know. If you want  to learn about widget programming, start  with
ref x. The graphics capabilities (lines, points etc.) are described in  ref
XpwGraphic.

If you want to lash up a quick control panel, quite a bit can be done  with
propsheets (see ref propsheet).  That's the route I  took with the  control
panel for my Scheme compiler, and it's not bad. You don't have much control
over layout, but it's easy to do.  My latest project is a simulated  marine
VHF radio to train myself to pass the Royal Yachting Association's VHF exam
(VHF has come to be standard equipment between my selling my first boat and
buying my second...).
