Based on the answer from waitinforatrain, which is not properly working for logged-in users (actually dangerous if you are using it in the back-end), I have modified it a bit and here it is, fully working for me. Please note that this is for Joomla 2.5.6, while this thread was originally for 1.5, hence the answers above:

function addJoomlaUser($name, $username, $password, $email) {
    jimport('joomla.user.helper');

    $data = array(
        "name"=>$name,
        "username"=>$username,
        "password"=>$password,
        "password2"=>$password,
        "email"=>$email,
        "block"=>0,
        "groups"=>array("1","2")
    );

    $user = new JUser;
    //Write to database
    if(!$user->bind($data)) {
        throw new Exception("Could not bind data. Error: " . $user->getError());
    }
    if (!$user->save()) {
        throw new Exception("Could not save user. Error: " . $user->getError());
    }

    return $user->id;
 }
