The 20-year-old made his Warriors debut in the win against Leigh and his start at Wolves was just his second outing.
He scored 20 tries in 22 games on loan at Championship side Swinton in 2016 on a dual registration deal, while also working as a trainee accountant.
"I'm really, really pleased for Liam," Wane told BBC Radio 5 live.
"His effort in training has been fantastic. With the pre-season he's had, he earned the right to play.
"I thought they were four quality tries and quality finishes.
"It is a shot in the arm for our youth system as it shows to everybody that a first-team start is never that far away. You just take your chances when they come and he's taken his."
Wane also confirmed that England forward John Bateman is expected to be out for three months with a shoulder injury.

Jennifer Fitzgerald's ex-boyfriend left the car at O'Hare airport's employee car park. She settled with the city out of court for $4,500.
The vehicle accumulated 678 tickets before it was finally towed last year.
Ms Fitzgerald said she had been unable to gain access to the car park, according to court records.
She continued to receive tickets even after the state of Illinois revoked the car's licence plates.
Ms Fitzgerald sued the city to clear the tickets and penalties.
Her lawyer, Robin Omahana, told DNAinfo Chicago the city had disregarded its own towing rules.
"They had a little egg on their face with writing so many tickets on one car," Mr Omahana said.
City law department spokesman Roderick Drew told the Chicago Tribune that the city had tried to settle with Ms Fitzgerald before the case went to court but she declined.
Under the terms of the settlement, her ex-boyfriend Brandon Preveau will reimburse her $1,600, with Ms Fitzgerald paying the rest on a monthly plan.

Local media reported that the man was driving the car when it crashed and later took his own life.
The men from New Zealand, aged 24 to 25, were on a hunting trip and not wearing seat belts, reports said.
Their families have reportedly arrived in Australia to arrange for their bodies to be flown back.
Police said they were preparing a report for the coroner.
The men were named by Australian and New Zealand media as Kadin Wallace, Jeremy Vergeer, and Dylan Sherriff, and were reportedly working on farms in the Esperance region.
Kadin Wallace, who was believed to be driving, survived the crash but is understood to have taken his own life before emergency services arrived, according to the Sydney Morning Herald.
Mr Vergeer got engaged just weeks ago and was the father of a child from a previous relationship.
His fiancÃ©e, Lauren Withers, posted a message to social media describing him as "my soulmate, my best friend, my everything".
"The future seemed so promising for us... 2016 was going to be the best year for us, buying our first home, getting married and moving to NZ to start our family," Ms Withers said.
