Tom Briscoe and Richard Whiting both scored two tries as the Black and Whites came from 10-0 down to condemn Warrington to only a third home defeat in two seasons. It was a third consecutive win for Hull since the return from injury of influential duo Gareth Ellis and Daniel Holdsworth, but Gentle has seen steady progress over the last two months.
"They clearly give us a lot of direction, but the key was probably being able to bring them back into a winning side," he said. "We've been building for quite a while. There's a real confidence about us. The boys have been working hard and they deserve plenty of credit."
Warrington were on course for a fourth straight win when tries from Simon Grix and Joel Monaghan gave them a 10-0 lead.
Briscoe pulled a try back four minutes before half-time and, although Ryan Atkins stretched Warrington's lead to 16-6 early in the second half, Hull went on to dominate the second half. Veteran half-back Richard Horne was the architect while Whiting and Briscoe provided the finishing touches.
"I still think there are things we can get better at," Gentle added. "We lacked a bit of composure in the first half. There was plenty of energy and enthusiasm but our execution could have been better and it was good to get a chat with them at half-time."
Warrington coach Tony Smith was gracious in defeat, admitting: "Hull deserved to win.
"They were a little bit more energetic than us in a couple of areas.
"There wasn't much between the two teams. They were both very committed to their defence and worked very hard to make it tough for their opponents to score.
"I'm pleased with the effort we put in. We weren't quite at our best in terms of handling but I can accept that. We just need to be a bit more clinical in these close matches."
