I also do not wish to start/rekindle/stoke any flame war that could be 
associated in the 2 coding styles. I know that it is a pain to connect 
the signals manually but the point in doing it would to have a fine 
grain control over your code, like what you want in this situation. That 
is why I think there are the two the options of manually connecting 
signals or having builder connect all of them for you.

  I agree that some other platforms, like C# with .net, make this 
somewhat easier. I would also argue that when building in Visual Studio 
there is actually more code being written to handle the interfaces, it 
is just generated by Visual Studio and not by hand. This is handy but 
also language and platform specific coding, the advantage of using Glade 
is the language independence of the XML file.

I would also agree that it would be nice to see a real GTK challenge to 
Visual Studio and QT Creator that has glade built in, multiple language 
support, and is cross platform. (Also that isn't MonoDevelop as they 
only support python on linux, which is sad because I would like to use 
it to build some nice python applications on windows.)
