it's not clear from your question:  Are you launching non-Python
programs from a python one, using Popen?  If so, I can't help.  It's the
launchee that determines if a console is created, as best as I know. 
However, if you're trying to launch a python program without its getting
a console, then read on.

No need for a multiplatform solution, since the problem is a Windows
one.  Windows will create a console for a new process unless the parent
console is still available (eg. you run it from command line) or unless
the executable is marked with the "no console" flag.  (I don't recall
what that's actually called, I haven't used Windows in a long time).

Anyway, in the Windows version, there are two executables  python.exe
and pythonw.exe.  You want the latter one, either by explicitly naming
it in your launcher (batch file, script, whatever), or by using the .pyw
extension, which is normally associated with the pythonw.exe program.
