Hey
@AntNYC - welcome to CF!
I've looked into this and it appears your only route to getting Windows on a new Mac is Parallels:

It appears Parallels is now free but you'll need to buy a Windows 10 or 11 licence.
You'll need to run Windows 10 or 11 ARM Edition but my research tells me that 99% of existing software "should" run on this. As you're trying to use a custom application, you might need to see if you can try it out at an Apple store or similar first to ensure your app will run okay, before spending a tonne of money.
The alternative solution would be to use some sort of remote desktop service, or buying a cheap Windows laptop just for the application - you can get second hand ones that will be adequate for most needs, and you could perhaps even set up a remote connection to it.
