get a dc power supply to start with.
walmart sells those cheapo power sources that put out 12v.

or an old cell phone charger, little lower power, but would do.

Or go the easy route and buy LED rope lights. We put them around our deck and they work quite nice. Plug and play. I think it was 20 bucks for a 25 foot rope.

I don't really want do rope because it's thick and I was just gonna do it along the corners but it was a good idea
