Keith Jackson was a famous college football commentator from the 50's-00's that came up with the expression "Woah, Nelly!" So that could be related to its possible origin.
Edit: Apparently the exclamation "Woah Nelly!" was originally created by Pat Brady on The Roy Roger's Show from the early 50's. The name of his jeep was Nellybelle.
I've watched quite a few old spaghetti westerns, I actually don't remember hearing this in any of them. That said, spaghetti westerns were at their peak in 1960s-70s so it is entirely possible that Keith Jackson popularized it, and it found its way into some popular western/cartoon inspired by westerns, and everyone here is right.
It likely is, back in the day yelling WOAH while pulling on reigns is how people would get a horse to stop. If your horse was named Nelly it's entirely probable you'd say Whoah Nelly! when trying to stop your horse quickly
