The 20-year-old has been a spectator in the past but his hopes of running out at Wembley were dashed 12 months ago when Wigan lost to Hull FC in the semi-finals.
The Warriors are hoping to go one step further when they meet Salford Red Devils in the second semi at Warrington on Sunday.
And victory would enable Gildart to follow in the footsteps of his father Ian, who was a member of Wigan's all-conquering side of the late 80s and early 90s.
"I used to watch footage of him walking out at Wembley," Gildart junior said. "He's been there a few times.
"My mum loves it, she hopes to be getting dolled up again. They've got some great memories from Wembley and hopefully I can make my own."

Gildart is still making up for lost time after suffering three fractures in his vertebrae during a league game against Leeds Rhinos in March.
He was forced to miss 10 matches but has played in the last seven and scored two tries in Wigan's 34-0 win over the Rhinos last Friday.
"I was getting a bit of form when I got that injury," he said. "I was gutted about that.
"But we're coming to the business end of the season and we've some massive games coming up, starting on Sunday. I've just got to keep putting performances in.
"It took me four or five games to get back into it - I was getting back pain when I went into tackles and it was affecting my carries. I was kind of not committing to things.
"But each week it's been getting better and for the last two or three games I've not felt it.
Great performance tonight roll on next week. Great to have @ant_crolla in the changing room thanks for the picture mate legend 👊🻠pic.twitter.com/w5aw7HY2X2

"I still get pain now on a morning, it's pretty stiff, and I will probably have that quite a while."
Gildart, who made his Betfred Super League debut for Salford during a brief spell on loan with the Red Devils in 2015, has already won a Grand Final ring and was in the Warriors team that lifted the Dacia World Club Challenge at the start of the year.
And he now wants to complete the set.
"Obviously I wanted to win a Grand Final and now the next one for me is Wembley," he said. "We're one game away.
"We just fell short last year and I was gutted.
"It's going to be a real tough challenge against Salford but we're confident."
