As said Korg M3 does not send any sound over USB, only MIDI. If you have Firewire EXB installed, then you can send sound digitally to your computer over FW.
If you have speakers connected to your PC then you should have kind a sound card there too. So you can hear your M3 through computer like that:
M3 (L/R out or digital out) --> PC soundcard input (analog or digital) --> Sound routed properly in PC --> PC soundcard output to speakers.

This question sounds like "what is the best tool to build house" or "what is the best car to ride road"
If you assume that "creating music " means "recording (MIDI or audio - something you play/sing on external instruments), editing, mastering etc" then some kind of DAW (they call it "digital audio workstation"). There are some free and many shareware/commercial ones available. Also as said many forums etc.
Hint: see people's signatures and you may get idea what they are using. Then you can ask in forums or PM: why?
