Add a "camera app" to my social network site

I have a website based on social-engine ([login to view URL]) The Site is optimized for phone and works fine. The site allows upload a photo and status. When you click on it it opens the device's built-in window You can select a camera and take pictures. I want to creat simple app the site to be in a "webview" - simple. And add a button below it leads to the camera nativ, And in camera , option to add filters, text on the image and so on. I know how to do just a webview. I need only(!!!) to create a native Camera app. done. only camera.!!! I drew a brief that explains what I need... This project is small so do not offer high!
