Replacing borland VCL library with visual studio 2019 supported UI libary

I have a project which use Borland v6 VCL UI libary and I want to migrate my code base to Visual Studio 2019, can u share an equivalent libary that I can use for UI level ? I dont want to pay for cross platform sw (QT framework), if you know a free libary that l can use, can u add them as a comment? The application is a desktop app, and I want to isolate UI level with business logic and want to implement MVC design pattern, is there a libary that will full fill that requirment?

Thanks Ben
