GUI on top of a big PowerShell PowerCLI script

Question

Hello, a very quick question...

I've built an orchestrator type of script in PowerShell/PowerCLI. It took me a while to build it and I am now asked to give it a GUI. No need to go fancy but a simple GUI that provides a level of abstraction for non experienced users. 

My questions:

 

1. Is it possible to put a GUI on top of a PoweShell script using WPF but without changing the script?

2. Do I need to study C# before using WPF? I handle JS, Angular, PHP and I did Java at University but that was long ago and I never used it.  

 

Many thanks for your time!

Cheers
