is there an open source app similar to SOAPScope?

Was wondering if anyone has built an app similar to SOAPScope
with Swing using WSIF?
 
If so can I get a copy ...
if not, would anyone be interested in helping me write this (and then
contributing this to open source)
 
Basically, I visualize a tool where you enter the WSDL as an argument
and will generate a JPanel with text fields per operation.
Other features include changing the soap address and generating
SOAP requests to a TextField that can then be modified by hand and
then submitted to the endpoint.
 
 
Cheers,
Henry
