Is it possible that one shoots from a corner and the ball directly goes into the goal without being hit by other players?
Has this situation occurred in an actual game (I mean not in training)?

Yes, it is possible to score a goal directly from a corner.
It has happened many times in professional leagues across the world as well as in international games.
This type of goal also has a specific name, being an Olympic Goal.
A small addition to the answer provided by @Orangecrush:
It certainly happens from time to time, but it would be a strong overstatement to say it's common. Goals from corners are usually due to extreme spin on the ball, external conditions (e.g. strong wind) or a blunder by the goalkeeper; more often than not a combination of these factors.
While it definitely takes great skill to score from a corner, it's hardly a smart or reliable way to take a corner, as in 9/10 cases it's an easy high ball for the goalie. What's different with Beckham's goal (first example by @Orangecrush) is that it's supposed to be a fast, low cross to the first post which is then hopefully tipped in by a teammate, or an unlucky defender. The fact that it goes in without touching anyone is just the irony of football, well and partially incompetence by both the defenders and the attackers :)
Hope it helps clear up the concept
