Question

I am creating a windows application using C#, where in a button on the GUI when clicked, should open a website.

The web browser will be taken care of by the default settings.

I am curious as to how to do that?

Answer 1

If the point is to open a website in your application, you will have to use WebBrowser control.
Put WebBrowser control on your form, and add this code to the button which is responsible for opening the site:

webBrowser1.Navigate("www.google.com");
