Ferrer, who has not dropped a set all week, won his first title on grass and also became the first Spaniard to win the Den Bosch tournament.
He was broken only once in 48 service games (saved 15 of 16 break points) during the week.
"I'm very happy with this win here in 's-Hertogenbosch," said Ferrer. "This was my first appearance here and it's great to win the title. This title means a lot to me, since it's my first title on a grass court. It also gives me more confidence for Wimbledon."
"Of course clay is still my favourite surface. This week I was playing very well, taking advantage of all my chances as I did for example in the quarterfinal against Ancic."
On being the first Spanish champion in 's-Hertogenbosch, Ferrer added,: "I think it's important for Spain to see that we start playing better and better on this surface as well. It's very nice to be the first Spanish champion in my first appearance here."
Ferrer broke Gicquel, who was appearing in his third career ATP final, in the opening game of the match and never faced a break point in the 42-minute set. The Spaniard only lost seven points in five service games. In the second set, Ferrer broke to take a 2-1 lead and then saved two break points in the sixth game. He broke Gicquel again in the next game to grab a 5-2 lead and then closed out the one hour and 22 minute match.
