Hi Sandy….fairly easy to do. If you are not using Jetpack which has a Widget Visibility feature, you can use a plugin called “Display Widgets” which is fairly easy to do compared to others that I’ve used such as Dynamic Widgets.
This tutorial for Circumference should help you out:

I should also mention that the demo link you gave me shows the custom header with captions option which you can also do. It’s a little more learning curve, but this Circumference tutorial will help you with that one:
