The 21-year-old had to bide his time after starting on the bench but he certainly made the most of his chance after coming on midway through the second half, although his goal owed everything to shocking back pass from Ronald Zubar which left the former Manchester City starlet with a simple finish.
"I'm absolutely delighted. It's always nice after the event when you bring in a player who you believe can score goals and he pops up on his debut to do that," said Coyle.
"But more than that I thought what he brought to the game when he came on - he was lively, he's got a trick, he's got composure as we saw with the goal, and it certainly augurs well for both the impact he'll make until the end of the season and indeed for Daniel's future."
The result made it three Barclays Premier League defeats in a row for Wolves, who dropped to the bottom of the table following West Ham's win at Blackpool, while for Bolton the victory ended a run of only one point from five games.
Coyle said: "It was a welcome three points. I think it would have been a travesty if we hadn't got them because of the chances we had tonight to get in front. We had numerous opportunities, balls whistling past the post, we just needed that bit of composure.
"I think, because of the little dip we had in January in terms of not getting the league wins that we've been used to, there's also going to be a nervousness that probably filters throughout the stadium. But the players stayed true to what we're doing, kept creating chances and I'm delighted."
Wolves boss Mick McCarthy, meanwhile, was left to reflect on another instance of his side shooting themselves in the foot.
"I don't really know what I can say after that, I feel lousy and I feel robbed," he said. "We had a point in our pocket but we gave it away. I think everyone had settled for a draw and there had been a few chances at either end and I was quite pleased with the potential point.
"I went and shook Zubar's hand to get his chin up and carry on playing. That is hard for all of us but that is what we have to do. He didn't mean to make a mistake but a mistake it was and we continue to make them."
