My iTouch is disabled but my dad del...

I bought an iTouch this past March. Around Late April my dad rebuild my laptop without telling me so my iTunes and every app, song, etc., got deleted with it. Soon, I was playing with my iTouch when I decided to change the passcode on it. Something went wrong and now I can't use my iTouch. I probably forgot what I changed it to two seconds after I changed it or I made a mistake typing in the new passcode, (but that seems unlikely). Ever since I've tried a number of times to figure out/break the passcode but not it is disabled. I read online that I could restore it so I downloaded iTunes on to my new laptop and restored my iTouch. Five times. So I'm guessing it would only work if my dad hadn't have erased all my iTunes stuff. I need help. Do you think I could bring it to Apple and see what they can do?
