Not with WMI, no.

I don't know how much overhead you are willing to impose, but you can always install a WH_CALLWNDPROC window hook and look for WM_CREATE messages.  That injects a DLL into every process in the system, so I'm not convinced it can be done with Python.  You may need to write a C++ DLL and have it communicate with your Python process.
