Help with minesweeper

[Brandalf]

Hey guys i dont know how to progress to finish off my minesweeper game i have no idea how to match the co-ordinates with the mines so that the player can find squares can anyone show me the code which will allow me to finish this game off as it is a starter project i cant seem to finish.
