how hard is it to learn this song Steve Vai - "For The Love Of God"

The main opening line isn't too tricky... The whole song would be hard...
What bit do you mean?

I am sure it may be possible to do some kind of version of it, but it's not likely going to sound even close to Vai. I would say try it and find out. Good luck. I would love to hear it. I am a huge Vai fan. Does your uke have a Whammy bar? Hahaha , kidding.
