Please don't use Glade.  The one piece of Glade-based UI we have is an
unmaintainable mess.  Besides, this functionality will be spread out
over the program to a large degree.

We already have a prefs setting use_menu_bar that determines if the
diagram window is in the right mouse button or a regular menu bar.  I
suggest you start by encapsulating that in a function gimp_like_ui(), so
it is isolated.  Then you'll also see where it gets used.

The current use_menu_bar setting is for new views; gimp/no-gimp UI
should be per-invocation, so for consistency new views should get the
menu bar setting from startup, not from the newest preferences, which
may have changed; the gimp_like_ui() function can hide that difference.
At the same time, the preference should move away from the new view
section in preferences.

At that point, new functionality would be easy to add, that's where your
above if-sentence comes in.  interface.c has most of the window setup
stuff.  Are you planning to do some kind of "docking" like newer gimp
versions, where things like layers dialog can fit in the same window as
the toolbox?
