Earlier, Thai qualifier Tamarine Tanasugarn defeated third-seeded Dinara Safina 7-5, 6-3 to capture her first grass-court crown.
The 31-year-old Gicquel, chasing his first ATP championship in a nine-year career, was overpowered by Ferrer in long baseline rallies at the warmup for Wimbledon, which starts Monday.
"I think this proves that we Spaniards can play well on grass,'' said Ferrer, the first Spaniard to win at Ordina.
Ferrer dominated the match with 12 aces and no double-faults. He had lost to the Frenchman in their two previous encounters.
"He was too good for me, I tried my best,'' said Gicquel, who was playing in only his third tournament final.
Playing with a bandaged thigh, Tanasugarn clinched the win with a powerful forehand winner.
Safina, the 2006 runner-up in Den Bosch and a semifinalist last year, said Tanasugarn was the better player.
"She has a lot of experience and she played well today,'' Safina said.
