X itself knows nothing about widgets or "fields". These are
constructed by the toolkit (GTK etc).
Also, with "lightweight" toolkits (which, IIRC, includes the latest
version of Qt), X doesn't even have any clues about how a window is
divided up, let alone definite information.
Realistically, you are going to need to handle each toolkit
separately, possibly even modifying the toolkit.
