Creating Lead automatically after BP creation

Hi Gurus

Here is the scenario. Our client has his own website. Whenever a customer opens the website and gives his details and select submit button, automatically a lead must be created. Is it possible. Please give me some approaches. Here are some approaches I knew

1. Making the customer to register directly in BP page which is linked to clients web portal. In this way a BP is created. Then we can ask the ABAP personnel to write a program to automatically create a lead.( is it possible).
