Maybe I'm stating something too obvious that you have already checked
but, since I didn't see any mention to this in your code, I will point
to it.

GTK+ has gestures support:

Here some examples:

I'm no expert on that but, as stated at:

I would assume that if you would set GDK_TOUCHPAD_GESTURE_MASK on
the GdkWindows of your widgets, you will have direct control for the
gestures and the context window would only be triggered by a press and
hold gesture (?)

As said, I'm no expert so maybe this is not so straight forward and/or
needs some modifications on WebKitGtk+ in order to work.
