How can I make a contact form plugin that send me mail to admin email just like feedback page?

Question

Because feedback page is not so informative. So I want to make a nice contact form plugin. I have made plugin.php and q2a contact page.php file.

With both files I can make a page from admin panel and by clicking the page link, The page can be opened but not send mail.

So how can i active this page so that it send me mail like feedback page..

Please anybody help..

How do you expect us to answer this question without seeing your code? We're not psychic. Do you have the plugin code in a public repository? Or can you edit your question and show the relevant part of your code?
