Three months after suffering an unhappy 5-0 Capital One Cup final defeat to Swansea, Bradford returned to Wembley to banish those demons with a committed display to blow Northampton away.
James Hanson, Rory McArdle and Wells were all on target in a devastating first-half display as Phil Parkinson's men cruised to a 3-0 victory.
Wells has been linked with a move away from Valley Parade in the summer following a series of sparkling displays, but the talented striker has pledged his future to the Bantams.
He told Sky Sports: "When you are doing well you grab the attention, but without the likes of these players keeping me going it wouldn't be possible.
"I'm contracted at Bradford and I'll be playing in League One next season.
"Dreams come true. We worked so hard to get here. To come this far and finish it off in this fashion is unbelievable.
"It's a big game, we wanted to come in confident but not arrogant. We went out there and did what we had to do and to win it comfortably like that is unbelievable."
Bradford skipper Gary Jones admitted it was a sweet moment to set aside the misery of their defeat by Swansea and secure promotion to League One.
Jones added: "It's unbelievable, it's probably the best moment of my life - apart from the kids being born, obviously.
"We thought we had unfinished business from the Swansea game. We came out with a game-plan. We knew Northampton were direct, we knew we had to get the ball down and play and the three goals were fantastic.
"Moments like this don't come around too often. We're just delighted today for everyone involved with Bradford City, the supporters have been unbelievable all season.
"Look at the fan-base we've got, we're geared up for League One, there's no reason why we can't do it."
