you could try something like:

file = r"\full\path\pythonw.exe"
os.spawnv(os.P_NOWAIT, file, (file, "program.pyw") + tuple(args))

note that spawnv doesn't scan the path, and that
you need to pass the name of the excutable as the
first item in the argument tuple.

the following sample script from the eff-bot guide
shows one way to locate the executable:

# File: os-spawn-example-2.py

import os
import string

def run(program, *args, **kw):
    # find executable
    mode = kw.get("mode", os.P_WAIT)
    for path in string.split(os.environ["PATH"], os.pathsep):
        file = os.path.join(path, program) + ".exe"
        try:
            return os.spawnv(mode, file, (file,) + args)
        except os.error:
            pass
    raise os.error, "cannot find executable"

run("python", "hello.py", mode=os.P_NOWAIT)
print "goodbye"
