I know how to do that. Here, let me break it down for you:
Firstly, make sure your poles are in place. For this example, I'll use PortGatePoleDwemer (located in WorldObjects/Activators). Line up the PorGateBaseDwemer (in WorldObjects/Static) with the poles and then place your button (WorldObjects/Activators) where you want it. Make sure that the poles are positioned how you want them when they are CLOSED. Once all of the necessary meshes are in place, we move on to step two.
Double click on the PortGatePoleDwemer and select the "Activate Parents" tab. It's in the row with 3D Data, Ownership, etc.
Right click in the white box and select "New". Another window will pop up.
Click "Select Reference in Render Window" and then use the crosshair to select the BUTTON. If you need a delay, you can fill it in under the "Activation Delay" box. The increments are in seconds. (I.E. "1.5" is one and a half seconds)
Now hit "OK" to close the new window and "OK" again to close the window for "PortGatePoleDwemer". Now this pole is controlled by the button. Repeat these steps for each PortGatePoleDwemer you need controlled.
Hope that helps
