Did you get a chance to read the FAQ on the three different ways that the switch can be used with SmartThings?
If you just use the standard DTH, which it should pair with automatically, you will then have two buttons on it. So you should be able to use it with anything that has a “button pressed” option, including the official smart lights feature or a routine.
As far as your hue bulbs, assuming they are already controllable from SmartThings (that is, they show up on your things list), just use smart lights and say you want those specific bulbs to turn on when button one is pressed and turn off when button two is pressed.
If you want to get more functionality out of it, there are two different community created DTHs that offer a different set of features. The FAQ explains.
