You'd be better off using localbitcoins. This tutorial is for selling Bitcoins, but buying them is essentially the same method. You just have to click on "BUY BITCOINS" at the top rather than "SELL BITCOINS."
If you're unable to figure it out, I may create a tutorial for how to buy BITCOIN, then STEEM, then add it to your Steemit wallet.
Coinbase, should have been a bit more specific :)
