it can be done w/ php ... simply have both forms action to the same page that they exist in and then have an if statement at the top of the page that redirects depending on which button was submitted ... ie.
<?
if ($button == "1") echo "1";
if ($button == "2") echo "2";
?>
<form method=get action=thispage.php>
<input type=submit name=button value=1>
</form>
<form method=get action=thispage.php>
<input type=submit name=button value=2>
</form>
something like that should do it
