web server

[flashgordone13]

Hello ,
I ask your help to make a program who will be a Web server written in C + + and listening with a socket through a predefined port (for
eg 8080). The program must send to any browser that a Web form
with three fields that the user must complete: an exclusive choice between encoding or decoding, an area
short text for the password (key), and a long text box to receive the message. The form also includes a button to submit the form content and a response from
server. This response is a simple Web page containing the text resulting from the encryption (or decryption).
I do the programs in c + + to encrypt or decrypt a message, and the html page as described in the subject but I don't know how to make a webserver.
I searched on internet for examples of web server in c + + either Linux or Windows but I have found nothing.
Please help me .
