The Canaries hit the lead through Jonny Howson in the 34th minute but could have conceded a spot-kick when Leroy Fer had pulled back Kenwyne Jones in the area only for referee Anthony Taylor to call play on.
After the match, Hughton felt that perhaps there was an element of luck involved, especially after Fer admitted to tugging on Jones.
"He (Fer) is an honest lad,” said Hughton.
"I have seen the incident, and yes, there is contact - I have to say, I thought the lad (Jones) made a meal of it.
"But if it is something we have got away with, then I think we are due one, as all Norwich supporters will tell you."
However, the Canaries boss was convinced his side deserved their hard-fought win at the Britannia Stadium.
"I think every win away from home is a big win, particularly for us, given we have found it more difficult away from home,” he added.
"I don't think there is anyone who would say different than we thoroughly deserved it. It is a big lift."
