PHP contact form with AS3

So I have searched the web, downloaded tutorials, watched videos and searched high and low for a simple to use as3 contact form. It seems that everything out there, is not all that simple, at least not for someone with my AS3 knowledge. I have a name, email and message field. Hit send, it sends the info and you get a thank you screen, that’s all I really need. I don’t need it to validate or to change the background color or anything fancy like that. Everything I have found has classes upon classes for these things to work.
Can’t it just be contained into one .as file for this to work?
If any one has any suggestions as to where to look for something like this I am all ears!

Thanks everyone!
