That's an easy one!
Look into CGIHTTPServer.py, near line 232:
            if self.is_python(scriptfile):
=>              interp = sys.executable
                if interp.lower().endswith("w.exe"):
                    # On Windows, use python.exe, not pythonw.exe
                    interp = interp[:-5] + interp[-4:]
                cmdline = "%s -u %s" % (interp, cmdline)

It tries to start 'sys.executable' with the python cgi script.  Normally
sys.executable is the Python interpreter, but for a py2exe'd script this
is the running executable (which is no longer a usual Python
interpreter).

Changing this line to 'interp = r"c:\python23\python.exe"' makes the
frozen script work (although then the Python installation is required
again).

(A few minutes later, looking at CGIHTTPServer.py again)
It seems you have to hack this module so that the code block starting at
line 270 is used, which says:
        else:
            # Other O.S. -- execute script in this process
and then it works fine.
