/** 
 * A funny code for your lover, which creates a frame that let her/him choose 
 * whether she/he loves you. If she/he choose 'YES', everythingis normal, but 
 * if she/he tries to choose 'NO', something interestingwould happen. First, 
 * the 'NO' button would change its position, it lookes like it attemps to escape 
 * from being clicked. After a couple of rounds, if she/he still want to click 
 * 'NO' button, the 'NO' button and 'YES' button will exchange their position. 
 * Besides, the window will cannot be closed untill the 'YES' button is clicked. 
 * 
 * To use this code, please make sure her/his computer has installed the JRE. 
 * 
 * Note that this code is just a little joke, DO NOT USE IT AS A REAL VALENTIN'S 
 * DAY GIFT, if you want to get laid at Valentin's Day, use ROSE, WINE and FANCY 
 * RESTAURANT, if you want to keep your mate's love, use YOUR HEART.
