External tool for editing Netbeans forms(NB4.1)?

Hi all!
I'm not sure if this is the right place to ask for that, so
please be patient:)
My questin is:
Is there any external tool to edit netbeans form files? I mean the
situation is like this: I'm working with NetBeans 4.1 on the same
project(and svn respo.) as my friends, who are working on
JBulider. And the problem is, that if I make some GUI form with
the NB designer, my friends aren't able to edit this form in
JBulider. So I would like to know if there is any "external GUI
editor" that can handle such forms from NB? So my friends would
edit GUI containers, without making and opening a project in
NetBeans?
The reason that they can't open my NB project saved in
the SVN respo, are path's - witch are of courese different on
Linux(me) and (Microshit;) Windows(my friends). Any ideas? Big
thanks in advance

Pedro
