There are two main ways to interact with UE4, Blueprints or C++. Blueprints are a visual scripting language. You can make a whole game just with Blueprints and never touch C++. Using Blueprints would probably be a good way to get started if you're familiar with programming but not C++. Once you sign up as a developer for UE4 you'll have access to tutorials, sample projects and forums. All of these can be useful learning resources.
