Buttons to open page inside html widget

I want to create 2 buttons and when I click on the first button I want to load a html page inside the html widget area and then when I click on the second button then I want to load another page inside the html widget. I guess using a class this is possible. How can this be done without having 2 html widgets?

Have a nice day,
