Well if the buttons you pushed were what you mentioned here, then it sounds like you set up the phone to do a "Hard Reset" which will wipe not only your apps, but any and all data you had on the phone. Photos, contacts, music, etc.
If you had the phone set to sync your files to google, then you may have the items there (if it updated regularly). Also if you saved the files to a SD card. However, if not for that, then it will all be gone.
