software installation - How to download quickbooks with Wine

I just installed Wine and I am trying to get Quickbooks Pro 2019 installed.
But I can't figure out Wine and how to use it. This will be our accounting software for quite a while. Ubuntu with the Aardvark is my version.

Any help would be greatly appreciated.
But please pretend that I am from Mars when you answer, because I am not the most literate Ubuntu user.
