I'm not aware of any such GUI, and even if one existed people would have to be 
trained to use it.  In contrast, we already have GUIs (e.g., Emacs) that people 
already know how to use and that work reasonably well with UTF-8 localedef sources.

Although the other goals you mention are laudable ones, surely they could be 
achieved by an automatic transformation of UTF-8 localedef sources into a 
less-readable equivalent with angle brackets, an equivalent that could be 
processed even by hypothetical tools operating in legacy multibyte locales. 
This shouldn't require a fancy GUI; it should be a relatively simple batch 
program.  Any engineering effort in this area would likely need this kind of 
transformation anyway, and any software developers in this specialized area 
should be able to take on this relatively minor extra task.
