    The software you need primarily, is the Source SDK.

    This is available over Steam at no charge.

    As far as how to use it to make a Portal Mod, Valve has been kind enough to provide a tutorial on that:

    For more information on using the Source SDK, take a look here:

    There is a ton of valuable information there, and it certainly provides a much better treatment of the subject than I could even begin to hope to do.

    Good luck.

    There is a mod called Gary's Mod. AKA Gmod. It is the biggest mod out there. I don't have it, but everyone that does have it says they enjoy it.

      Gmod is a game, not a P2 mod.
