Gateway Laptop

Is there any way I can run a mac software bundle on my gateway laptop?
In my program of study its mandatory to have a laptop..so I just got a new gateway this past christmas. But now there saying we should really have a mac. I don’t need two laptops so I’m wondering if I can run the programs such as garageband and imovie,etc on my current laptop?
You might have to find an emulator and load the Mac OS in there to get to your apps.
