PowerShell Simple GUI?

I have a PowerShell script that does some automation stuff. However, there are 2 variables that need to be hardcoded or entered by the user.

I am looking for a way to make a VERY simple GUI that simply presents the user with 2 text boxes in which they enter the information and then the information is written or loaded into the script. And of course, a simple run button that would run the script.

I am hoping someone can help me with this or point me in the right direction for someone with no experience at all with GUI creation.
