simple code

I have an audio file i want to link this audio file with a program. the program should do the following: *it should contain a start button in which when I press it the main audio file plays. *the program should also contain a box in which a user can type in a passcode (the passcode can be char or number or a combination of both) when the user presses the enter button if the pass code is correct the main audio file stops and another one plays. if the code is wrong a buzz sound plays on top of the main audio file without interupting it. *if the pass code entered is wrong the main audio file keeps playing normally to the end. *also i need the follwoing buttons (play, stop, reset) *also i need the main audio file timer to be displayed in which i can manipulate if something goes wrong. * i need the tracker to be sit on the box file in which when i start the program and type in any thing it gets typed in the box and the enter button on the key board to be linked with a submit button to check if the code is correct or not and act accordingly.
