I have a bunch of these for Gtk--, but not for GTK+. In particular, I
have:
MotionFeedback - a widget which cycles through a set of
pixmaps to reflect various kinds of mouse
motion and/or keyboard input. By changing the
pixmap sets, you can get totally different
visual appearances - for instance, there is
no difference between a fader and a knob
except the set of pixmaps that they both use.
MidiControllable - a virtual object which can be hooked up
to incoming MIDI signals from my libmidi classes.

i have such a beast for GTK+. Its a variant of the gtk curve widget. I
can't remember right now what it does, but I use it for the Enveloper
visual element in gtk-quasimodo. It allows up to 6 set points.

But the canvas widget isn't part of GTK+ ... please don't make us use
GNOME :) I don't how close the versions of these things in Quasimodo
are to what you mean, but they might be good places to start. I have a
Gtk_Ellipsoid widget for Gtk--, which draw dangling patch cords
between two points. It uses my own mini-canvas GTK+ widget,
GtkTransparency, which allows for multiple draws/erases in the same
area and is more efficient (though not as flexible) as the GnomeCanvas.
If anyone wants to look at any of this stuff, its in the src
distribution at http://www.op.net/~pbd/quasimodo/
