using my macbook or airport as a router

[springac]

I have an Intel Macbook running 10.5, and I get the internet through a 3G usb modem from my wireless company. Can I share this internet connection via a wireless router to other WiFi-enabled computers? Do I need to have an Airport Extreme base station or just the software?
Which option is best for including a PC in the wireless network?

Thanks for the help

No, you don't need a Airport station to share an internet feed.
Just make sure that the sharing computers are wirelessly networked(or Ethernet) and using Sharing in System Preferences select the Internet tab and go from there.
