Wurst isn't a language, it's a syntax which is just another way of typing the actual powerful scripting language JASS which isn't that powerful... It's just quite powerful in terms of modding and what you can do with it however sadly it still doesn't give you much power as its very slow.
Though yeah currently your out of luck unless your good at learning by yourself, you might be able to find some Wurst resources on here though to learn from.
