Create Google Groups Topic: PHP Script

I need a PHP script that posts a new topic on a Google group board that I am the manager of. The script should take in the following parameters: Input 1: Group email address Input 2: Google email address Input 3: Google password Input 4: Topic subject Input 5: Topic message The script should then create the topic based on the supplied subject / message. Once complete the script should output the URL of the successfully created topic. If the topic creation has been unsuccessful the script should output the reason for failure. The script needs to be PHP. I am guessing you will need to use CURL but if you can use any APIs then feel free to do so. No GUI is necessary. The input variables can be hard coded. NOTE: If you come in lower than budget you have more chance of being hired. Contact me if you need any other details.
