Which BDD framework allows a simplistic approach to "story writing"?

Question

I'm trying to use BDD in a very simple way, in order to minimize the amount of Java code. I want to create exactly two files, one is my story:

Given user is named "John Doe" 
And user is authenticated
When user changes his password to "a1b2c3"
Then user password equals to "a1b2c3"

Next, I create a Java class:

public class UserManipulator {
  @Given("$user is named $name")
  public User shouldExistOrBeCreated(String name) {
    User user = //...
    return user;
  }
  @Given("$user is authenticated")
  public void shouldBeLoggedIn() {
    // ...
  }
  @When("$user changes his password to $pwd")
  public void shouldChangePassword(User user, String pwd) {
    // ...
  }
  @Then("$user password equals to $pwd")
  public void shouldHaveThisPassword(User user, String pwd) {
    assertEquals(user.getPassword(), pwd);
  }
}

And that's it. I don't want to have any more files, any more unit tests. I want some BDD-framework to find my story file, parse all my Java files, and run them one by one. Is it possible to achieve?

ps. What is important here is a possible reuse of Java methods in my other stories. For example, this is the story no.2:

Given user is named "Michael Doe"   <-- reuse
When user adds $100.00 to his account
Then user account balance is $100.00

You want to have a look at:

• easyb,
• or JBehave ant its Getting Started guide,
• and maybe Specatular and its Getting Started guide.

Also, this presentation on BDD in Java and Groovy could be of interest.
