Answer 1

First Add a button to your form and in the Click event handler do this

private void button1_Click(object sender, EventArgs e)
{           
   //remove this from the constructor else it will be loaded along with the form
    webBrowser1.Navigate("http://www.google.com");
}

Answer 2

public partial class Form1 : Form

{

    bool mHooked;

    public Form1()

    {
        InitializeComponent();
        webBrowser1.DocumentCompleted += webBrowser1_DocumentCompleted;
        //webBrowser1.Navigate("http://www.google.com"); 
    }

    private void button1_Click(object sender, EventArgs e)
    {
        webBrowser1.Navigate("http://www.google.com"); 
    }
    void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) 
    {
        if (mHooked) return;   
        // Get the form 
        HtmlDocument doc = webBrowser1.Document; 
        HtmlElement form = doc.Forms["f"];    
        // Get the "I'm feeling lucky" button 
        HtmlElement lucky = form.All["btnI"];
        lucky.Click += button1_Click;   
        mHooked = true;   
    } 
}

Answer 3

On Click of button add:

ProcessStartInfo sInfo = new ProcessStartInfo("http://mysite.com/");  
Process.Start(sInfo);

(or)

System.Diagnostics.Process.StartProcessStartInfo sInfo = new ProcessStartInfo("http://mysite.com/");
Process.Start(sInfo);

If you want to use web scraping technique to extract data from the particular website or open the website in your winform itself then use web browser control and try anyone of the answers provided by ShaliniPavan or V4Vendetta.
