Purchasing Steem?

As a new Steemian, I often look at trending posts about Steemit' and Crypto Currency and feel very out of my depth. Thanks to people like Hive account@davemccoy I am slowly but surely learning to navigate my way around and understand some of the jargon.

When first attempting to buy Steem', by following the link in my wallet, I discovered that, I could only purchase it using Crypto Currencies. Following advice, I opened an account on Coinbase, which I have yet to use, but I don't know yet, how to link it to my wallet, so I can convert other currencies into Steem'.

With Each Answer, Further Questions Arise

So Here's My Question
I'd rather risk looking foolish, than not find out the answer, besides, I'm sure there are others like me out there, who have questions that they're afraid to ask at risk of looking stupid.

So here's my question:
Is there a way of buying Steem, using good old fashioned cash in just one easy step?

For all of us out there, who have yet to accrue a Crypto Currency portfolio and have never been involved in investments or trading until now, could adding an option in the wallet to purchase Steem using Sterling or Dollars (or other traditional currencies), be a possibility for the future?
