When writing GUI code directly in the programming language you can
separate the presentation from the functionality in several ways.  A
simplistic solution is using a table that specifies what item goes where
and putting that table separately from the code that implements the
items.  There are many other ways, of course.

The problem of using a separate file for describing the presentation is
that this is yet another file format.  This quickly turns into another
language.  The result is that you get stuck with one tool that can
handle the language in a nice way, or you need to edit it directly,
which means you have to learn that language.

A separate description of the presentation works well for static things,
like a dialog, but not for dynamic things.  I have found that using Boa
Constructor with wxPython works very well for both.  I have used it for
Agide (although I manually changed a few things that caused Boa no
longer being able to edit the code in the designer).
