Willowtree is an xbox360 modding program

No, Skyrim PC mods do not work on Xbox 360. The two platforms use different file formats and systems for mods, making them incompatible. While the Xbox 360 version of Skyrim does not support user-created mods, the PC version allows extensive modding through various tools and platforms like Nexus Mods. If you're looking to use mods, you'll need to play on a PC or a platform that supports modding, like Xbox One or Xbox Series X/S via the Bethesda.net mod platform.

You can use a modding software for that. Download the mods from a Modification website and then use the modding software to install them to the game.
