I will refrain from commenting the entomologist's latest posting.  I
will instead give a few examples of what I mean by:

The first example is Ibuild, a user interface builder that is part of
InterViews 3.0 (currently in alpha-release).  The user composes
several predefined graphical and interactive objects with a graphical
editor.  When the design is complete, Ibuild can generate a set of .h and
.c files that implements this user interface.  The code is not complete
-- the behaviour of interactive objects must be added afterwards, for
example.  Ibuild will also generate a small "main" program so you can
test drive the user interface.

The second example is TeleUse, another user interface management
system, although for C and X11.  This is a rather more mature
(commercial) product.  I believe the output of TeleUse requires much
less hand-crafting than the Ibuild output.

The third example is not directly related to C++, but perhaps the most
interesting because it goes beyond computer programming.  Simnon is a
simulator package for non-linear systems.  It provides a complete
interactive environment for simulation of models based on non-linear
differential equations.  Simnon is a useful package, for example for
designing a control system.  There is an additional package that takes
Simnon code as input and produces Modula-2 code suitable for
implementing a controller on an IBM PC (there is also a small runtime
library that provides initialization and a simple graphical user
interface).
