Question

I am trying to get started with git, and am using Git GUI. I have my pre-written code, created a repo in it’s directory, but cannot push, as there are no branches. When I try to make one, it wants a “Revision Expression”. I don’t know what that is.

Answer 1

You push to a remote repository.

What you want to do is git add and than git commit.

I suggest, you work yourself through the git school to learn the basics.
