Is there an example for how to rewrite the simple Checkout button form post code as a link?

for example:

Convert

<form name="PrePage" method = "post" action = "https://Simplecheckout.authorize.net/payment/CatalogPayment.aspx"> <input type = "hidden" name = "LinkId" value ="9627a9fc-80a9-4656-a11d-3283f10962fb" /> <input type = "image" src="//content.authorize.net/images/buy-now-blue.gif" /> </form> 

to 

<a href="https://Simplecheckout.authorize.net/payment/CatalogPayment.aspx">buy now</a>
