Gas is like electricity; you need to respect it, but don't need to fear it. It's much like electrical work in that way. However, gas is a lot more straight-forward than electrical work. The consequences are very bad, so the manufacturers make it almost fool-proof to mess up. It's not like other gadgets where you need to get a proprietary widget to hook it up; the liability is just too high and so they are standardized. Just go to your local "big box" home improvement store and get a range connection kit. Should have a yellow corrugated metal hose and miscellaneous parts. It will have everything you need except the wrenches. Should be straight-forward, but read the directions over and over until you gain the confidence. Should be as simple as tightening two connections and then opening the valve. As mentioned above, test with a soap/water solution. The mantra is "no bubbles, no troubles". If you see bubbles, shut off the valve and tighten the connections more. Lather, rinse, repeat.
Good luck!
