One layer of the mess that X has become.

bottom layer X provides a "wire protocol" for sending graphics requests
over a network.

xlib provides basic programming interface to above from C.

xt provides C programming infrastructure to do OOP/GUI (Object Oriented
Programming/Grahpical User Interface) programming.  Fresco (if it's still
around) imitates xt functionality in C++ and provides a library of actual
graphical objects as well.

MOTIF provides a library of actual graphical objects using xt and is the
lowest layer that a real human programmer should consider dealing with.  It
also provides a window manager program which takes care of things like
title bars and letting a user move windows around.

AFAIK most real X programming these days is either done using a builder
tool that creates an application skeliton using e.g. MOTIF objects or using
prototyping tools like the tk library in tcl.

Signature failed Preliminary Design Review.
Feasibility of a new signature is currently being evaluated.
