Info about RAD tools

Hi, I am new to wxPython. Looks Great!

I want to build a GUI app with a RAD tool like wxGlade or wxDesigner or one of the others that seem to be out there but I just want a XML description of the resource (XRC?) not auto code generation. Is XRC stable and usable at this point. None of the (Very cool) demo scripts seem to use it -- the dems just show laying out GUI with code snippets.

What is is best RAD tool to use at this point? Will they all share the same XRC files if I switch later?
wxDesigner looks ok, but I want my resources to be in text form not in some proprietary binary format...

The other thing I am worried about is i18n issues. How are people coping with that.. I can't get the i18n people I work with some confusing new tool just so they can edit the text of the dialogs -- they like to edit plain text files. I want something like _N("My Translated Text") but for the GUI XML.
I can build the tools do this stuff myself, but I don't want to re-invent the wheel needlessly.
