Whitney has been in a relationship with Fatboy Chubb (Ricky Norwood) in recent weeks, but she remains secretly attracted to local womaniser Tyler Moon.
McGarty told Inside Soap's Yearbook 2012: "I personally think that it'd be lovely if Whitney and Fatboy could live happily ever after in Walford. Deep down though, I reckon that Whitney knows that Tyler's actually the guy for her. She does like her bad boys, doesn't she?
"Tyler's not that bad in reality of course, but he still has that little bit of an edge - like Billie Jackson did when she was going out with him. I think she knows Tyler is going to be the one for her."
The actress also suggested that Bianca Butcher's forthcoming EastEnders return will have a positive impact on Whitney.
"I think it's worked really well for Whitney's storylines this year that she's felt quite alone, but now is definitely the right time for Bianca to come back," she said. "Whitney just needs her mum in her life."
Tony Discipline, who plays Tyler, recently claimed that the antiques dealer "understands Whitney more than anyone else".
