So let's write one in Python in a minute!

---- winmem.py
from ctypes import *
from ctypes.wintypes import *

class MEMORYSTATUS(Structure):
    _fields_ = [
        ('dwLength', DWORD),
        ('dwMemoryLoad', DWORD),
        ('dwTotalPhys', DWORD),
        ('dwAvailPhys', DWORD),
        ('dwTotalPageFile', DWORD),
        ('dwAvailPageFile', DWORD),
        ('dwTotalVirtual', DWORD),
        ('dwAvailVirtual', DWORD),
    ]

def winmem():
    x = MEMORYSTATUS()
    windll.kernel32.GlobalMemoryStatus(byref(x))
    return x

---- in your code
>>> from winmem import winmem
>>> m = winmem()
>>> print '%d MB physical RAM left.' % (m.dwAvailPhys/1024**2)
90 MB physical RAM left.
>>> 


Hail to ctypes!

If you have never heard of ctypes, visit
http://starship.python.net/crew/theller/ctypes/ and try it. You
will love it.
