The main window should be non-resizeable without a menu. You should have a clear button to reset the game and a system menu that allows you to quit.
Moves consist of the user clicking on the place they want to move.
If the user trys to click on a previously chosen location, the move is not accepted and a nasty comment about cheating appears in the game log. Finally, if the game is a draw or if someone wins, this should be recorded in the game log also. The following images show the game after a win and after a draw. This is the transcript in the case the user tries to enter the same square. The log should scroll so that the current move is always visible.
