I've never worked with cuke4php. I've only installed (once) XAMPP on a WinXP SP3 system, and don't really know how to configure it (I'm a ColdFusion developer who took some PHP tutorials out of curiosity.)
But I believe that Apache does have a stand-alone Windows installer; install it and follow instructions on how to get PHP working on it, then you can use that for feature testing.
