Command & Conquer Generals Launcher Apple Script

I’m trying to create a script that’ll do the following:
give an open file window of the folder /Applications/Command & Conquer Generals/Mods Data/
After selecting the mod you wish to run
it would’ve to move that file to the folder /Applications/Command & Conquer Generals/Generals Data/

And would it be possible to move the mod back to the Mods Data folder when selecting another mod?

Can someone please help me?
