I can send you a browser I wrote (in Java) which executes all seven main HTTP methods. It's basic, but good for this sort of testing - and (for curiosity) you can look at the source code.
It is on my web site, but wrapped up with some other stuff - might be easier if you drop me an email directly, and I'll return a simpler JAR file.
HTH,
