I mean if you're learning, the best thing to do is just keep on coding, because the more you do it the better you become.
But, making something like won't really increase your knowledge
This is simply drag a webBrowser onto your form, a few buttons with these statements;
webBrowser1.GoForward();
webBrowser1.GoBack();
webBrowser1.Naviate("Link"); //Your textBox
webBrowser1.Refresh();
The inbuilt webBrowser in VS is complete and utter crap, and I think most people would prefer to use something like Google Chrome
Not hating, by the way

Good Job!
