Without knowing what sources you have already looked at, anything anyone
might say might be duplication. However,...

If the builtin hardware sound generator only generates integral
frequencies, you are stuck unless you get an add-in card that is more
flexible. If the Windows interface to the hardware only accepts
integral frequencies, which I suspect might be true, ditto, unless you
get custom software. You could look at pygame and see what its sound
functions do. And search pypi for 'sound generator' or 'frequency
generator'.
