You need to subscribe to the button click event, and then you need a block of code like this:
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
message.To.Add("luckyperson@online.microsoft.com");
message.Subject = "This is the Subject line";
message.From = new System.Net.Mail.MailAddress("From@online.microsoft.com");
message.Body = "This is the message body";
System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("yoursmtphost");
smtp.Send(message);
Just set the message.Body property to the contents of the Textbox's, and set the subject accordingly. This is basic stuff and there are many examples to be found on line.
You will need an SMPT server, you could use Gmail for that. Just look that up on Google.
