window question

I’m needing to script the QuickTime player under OS X and am new to AppleScript. How do I tell the QuickTime player to bring a specific, already-open window to the front? Because the movies are already open, I can reference them by name.
Thanks

I don’t know X but this works in classic…

set x to (choose from list (get name of windows of application "QuickTime Player")) as string 
if result is false then return
 tell application "QuickTime Player"
    activate
   select window named x 
end tell
