//Google Form Key
$formkey = "dFdDTFBFRG1yZm9MckZUanFuM2dEd1E6MQ";
//Email address of person who should get email notification of form submission

 ";
$thankyou = "http://www.jazzerup.com/blogexamples/googleform/thankyou.html";
//Change this URL to your google form address
$googleformURL = "https://spreadsheets.google.com/formResponse?formkey=$formkey";
//-----------------Start send email script------------------------
//This is where you would put any custom scripting such as using php to send confirmation emails
$name = $_POST["entry_0_single"];  //Replace the periods in the field name with underscore.
$fromemail = $_POST["entry_1_single"];
$subject = $_POST["entry_2_single"];
$body = $_POST["entry_3_single"];
$header = "From: " . $fromemail . "\r\n";
$header .= "Reply-To: " . $fromemail . "\r\n";
if (!(mail($toemail,$subject,$body,$header))) {
   echo("
<p>Message delivery failed...</p>
 
");
   echo("from email: $fromemail to email: $toemail");
  }
//-----------------End send email script------------------------
 
//----------------Send Form Fields to Google--------------------
//Loops through the form fields and creates a query string to submit to google
foreach ($_POST as $var => $value) {
 
    if ($var != "ignore") {
    $postdata=$postdata . htmlentities(str_replace("_", "." , $var)) . "=" . $value . "&amp;";
    }
}
//remove the extra comma
$postdata=substr($postdata,0,-1);
//Submit the form fields to google
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL,$googleformURL);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
curl_setopt ($ch, CURLOPT_TIMEOUT, 60);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt ($ch, CURLOPT_POST, 1);
$data = curl_exec ($ch);
curl_close($ch);
//echo $data;
//Redirect to your thank you page
header( "Location: $thankyou" ) ;
 

Now that you have a custom form page you can add a captcha to it if you want.
