I`d like to learn english language alone, without any help of teacher. What textbook(tutorial) i must buy?

I really, really would not recommend that. Like... at all. Even native speakers of English learn from teachers. There is only so much Bücher can teach Du about language.

[url="http://www.esl.net/textbooks.html"] here is a Liste of good Bücher and programs commonly used for people who are learning English as a Sekunde language. But I would highly recommend using these as secondary resources and getting a teacher oder mentor.
