GUI for Powershell script to create a Windows installation disk

Question

I have this powershell script that creates a Windows installation disk.

-For both Legacy BIOS and the native UEFI boot process.

-For systems that use UEFI with Secure Boot

-For Windows ISOs that have Install.WIMs that are over 4GB (Due to the 4GB limitation of FAT32).

What the script does is:

-It creates 2 partitions on your USB disk. A FAT32 and an NTFS partition.

-Mounts the Windows ISO.

-Copies the entire contents of the ISO to the NTFS partition of the installation disk.

-Then copies all the boot files from the ISO to the FAT32 partition of the installation disk. (“boot” folder, “efi” folder, “bootmgr”, “bootmgr.efi” and “boot.wim”)

I'm trying to modify the script so as to have just a GUI to create the Windows installation disk. But I have a very limited knowledge of scripting, so this is as far as I got.

This is the script I have so far:
