Waddock set his sights on celebratory scenes in 12 months' time after falling to a 2-0 defeat at Sheffield Wednesday which clinched the South Yorkshire club's promotion to the Championship.
Michail Antonio gave the hosts a 25th-minute lead following a burst into the area. Wycombe keeper Nikki Bull, who had kept the Owls at bay with some fine saves, was beaten again by Nile Ranger's 52nd-minute header.
Waddock said: "We were up against some big clubs at this level.
"Hopefully in a year's time we'll be able to get back to this level. We need to bring in some new faces.
"I thought we handled it very well here. We had a few young players out there and it was a fantastic atmosphere."
