It's possible, but I wouldn't do it for your given use case :) (the UI could be done with the Android framework)

You can add what they call "Javascript Interfaces", which are basically links from Javascript to Java code. First, define a class to bind containing the methods you which to call, and add it to your WebView :

    class HelloInterface  
    {  
        public void test(String name)  
        {  
            Log.i(TAG, "Hello " + name); 
        }  
    } 

    webview.addJavascriptInterface(new HelloInterface(), "HELLO");

Then, from your javascript code, you can just call 

window.HELLO.test("Webview");

its actually reall easy (and cool) use:

webView.addJavascriptInterface(js, "pageObject");

js is a java object made in you activty (or somewhere where you init the webview), pageObject is the namespace identifier (variable) you can use with javaScript on your webpage.
