Wigan coach Shaun Wane spoke of his joy after masterminding a record-extending 19th Challenge Cup win for his home-town team.
Full-back Sam Tomkins and centre Iain Thornley scored the only tries of the lowest-scoring final for 33 years as the Warriors overcame Hull 16-0 at Wembley.
"We were in control, all credit to the players," Wane told BBC1. "The conditions were poor and credit to Hull, they had a real dig, but today was our day.
"It's a joy, they're a great bunch of players and I've got a fantastic staff.
"To come to this great stadium and get a win like that against a quality team is what dreams are made of."
Wigan's other points came from winger Pat Richards, who kicked four goals from four attempts on his last Wembley appearance as he prepares to return home to Australia, but the Lance Todd Trophy as man of the match went to scrum-half Matty Smith, whose kicking in the difficult conditions proved crucial.
"It means everything," Smith said. "It's what all the aggro is for, to win trophies like this.
"This is the reason we play the game, to lift that trophy will be something I'll never forget.
"It makes it an even game when conditions are like this. We had to complete our sets and kick well. We knew it was going to be close. They're a fantastic side but it was just our day."
Wigan dominated the first half but led only 6-0 thanks to a solo try from Thornley, who said: "I got a bit of space, two on two, and just took the chance and luckily I got over the line.
"With the attacking ability both teams have got, I thought there'd be a few tries but it shows how tough the game is today."
Tomkins completed the scoring in the last minute with his 11th try of the 2013 competition, which will almost certainly be his last for some time as he prepares to leave the club at the end of the season.
The England full-back is widely tipped to join New Zealand Warriors on a three-year deal but, despite appearing to wave goodbye to the Wigan fans among the 78,137 crowd, he remained tight-lipped over his future even as he celebrated his second Cup success in three years.
"I was waving there because I'd just scored a try at Wembley, no other reason," he said.
"I'm here to play in the Challenge Cup and win with Wigan, not to talk about that.
"This means everything. We know the tradition of the cup and these tens of thousands behind us know what it means."
Hull became the first team to be nilled in a final since Wigan beat St Helens 27-0 in 1989 and today's defeat leaves them still searching for a first win at Wembley.
"We couldn't hold the ball," coach Peter Gentle told BBC1. "We still only conceded two tries so credit to our defence but, if you can't hold the ball, you're not going to win.
"We spoke all week about having an even share of possession but they were too good for us in all facets.
"We gave them a good leg up - there were four or five sets in a row there where we didn't get past tackle two - you can't win doing that."
