Sadly, no. My first WC game was WC4 and then WC3. Didnt get to play the first two until years later when I bought a used copy of Kilrathi Saga on eBay. Totally worth it, though.
I have heard a great deal about Privateer 1. And 2, although many consider that one not as 'open' as the first one. Wished I could have played them.
It's your lucky day! You can buy Privateer and play it legally right now!

It's fairly common on ebay, too.
If you don't want to spend any money, you can try Gemini Gold, but it's not quite the same as playing the actual, original game.
