Is it possible to create a form submitting to a php file?

I guess it is not possible, but i ask anyway:

I want to create a form, with three fields and a submit button. the variables is submitted to a php file (action="script.php"), and the script returns a text string.

Is this possible to make?

For example, index.wml:

<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.3//EN" "http://www.wapforum.org/DTD/wml13.dtd" >
<wml>
<card>
<p>
<select name="destination_number">
<option value="test">Here</option>
</select>
<input type="text" name="message" emptyok="false" maxlength="130" size="33" />
<do type="accept" label="submit">
<go href="process_form.php" method="post">
<postfield name="destination_number" value="$destination_number" />
<postfield name="message" value="$message" />
</go>
</do>
</p>
</card>
</wml>

you'll have $_POST["message"] and $_POST["destination_number"] available on the process_form.php script...

Hope it gets you started...
