You can host a web page in a WPF application using the WebBrowser controls that was added in .NET 3.5 SP1:

<Grid>
    <WebBrowser Name="browser" />
</Grid>

And in the code-behind you have to set the Uri to your page and an object (which should be com-visible) that is to be called from the java script:

public partial class Window1 : Window
{
    public Window1()
    {
        InitializeComponent();

        string uri = AppDomain.CurrentDomain.BaseDirectory + "TestPage.html";
        this.browser.Navigate(new Uri(uri, UriKind.Absolute));
        this.browser.ObjectForScripting = new ScriptingHelper();
    }

    [ComVisible(true)]
    public class ScriptingHelper
    {
        public void ShowMessage(string message)
        {
            MessageBox.Show(message);
        }
    }
}

And finally in your page you must call the code using window.external like below:

<head>
    <title></title>

    <script type="text/javascript">
        function OnClick()
        {
            var message = "Hello!";
            window.external.ShowMessage(message);
        }
    </script>
</head>
<body>
    <a href="#" onclick="OnClick()">Click me</a>
</body>
