Visual Basic (any flavor) is different from AppGameKit Basic.
Action Script (which is what I assume you mean by 'AS') is of little or no help with AGK.
PHP is useful only if you are going to host your own leader board (as I do, www.triassicgames.com/scores.php).
I am guessing that you mean that you are not very good at game programming when you say 'I am not rlly good at that kind'.
Have you purchased AppGameKit yet?
If so, you can look at the various Tier 1 examples to see how some things are done in AGK.
If not, purchase it and then look at the example programs.
