You can do like this

    <?php
        if(isset($_REQUEST['searchbutton']))
        {
    ?>
     <a href="http://www.example.com?q=<?php echo $_REQUEST['q']?>" target="_blank">Hello</a>
     <?php 
    }

?>

If you are using jquery in your project and want to do this on the front end, you can do:

<a id="someLink" href="http://www.example.com/?q=var" target="_blank">Hello"</a>

$('#someLink').attr('href', "http://www.example.com/?q=" + $('q').val());

With php you'd only be able to set the entered value of q on a post. (meaning when someone submits the form)

i.e.

<a href="http://www.example.com?q=<?php echo $_POST['q']; ?>" target="_blank">Hello"</a>

IF you need to populate the link href without a page refresh, you'll need to use javascript, if you want it to be populated after a form post, you can use php.

Be aware though that the link would need to be on the page set in your forms action attribute to populate the link

You should be aware that you take precautions when echoing out form submissions, however the level of questions suggests you've got more to learn before that. (No offense intended)

<form id="searchform" action="fetchvalues.php" method="get">
<input name="q" id="q" type="text" />
<input name="searchbutton" id="go" type="submit" value="" />
</form>

On your fetchvalues.php page

 <?php
    $val = $_GET['q'];
 ?>

then

<a href="http://www.example.com?q=<?php echo $val; ?>" target="_blank">Hello</a>
