I think it goes beyond "no", all the way to "heck no".
Nothing in Pandora is directly accessible via AppleScript.
From the olden days (2005?) I remembered using Apple's UI Element Inspector to discover things that can be accessed via AppleScript. There's nothing accessible in PandoraOne: the entire thing appears as a single opaque object.
If you're still willing to take a shot at it, you'll probably want to use Apple's "System Events" Scripting Addition and use the "Click at {x, y}" event, but be aware that X and Y are screen coordinates, so you will have to get the location of the PandoraOne window and calculate offsets from that to hit the buttons.
Like i said, pretty much "heck no".
