You probably don't want the exec call in the onClick property of the 
input button, but rather in the PHP script that is the action of the 
form. Something more like this:

<?php
echo '<form action="game.php" method="post">';
echo '   <input type="submit" value="Start" name="action" />';
echo '</form>';

echo '<form action="game.php" method="post">';
echo '   <input type="submit" value="Stop" name="action" />';
echo '</form>';
?>

And then, game.php looks like this:

<?php
$twl = "C:\\pathtobat\\twladv.bat";
$action = $_POST['action'];
if( $action == 'Start' ) {
    echo "Starting...<br />\n";
    exec( $twl );
    echo "Done!<br />\n";
} elseif( $action == 'Stop' ) {
    echo "Stopping...<br />\n";
    exec( "c:\something\else.exe" );
    echo "Done!<br />\n";
}
?>

That ought to get you pointed in the right direction. The exec() call 
should definitely not be in the JavaScript onClick property of the 
input. Good luck!.
