If i understand you right, you want to switch the tabs from tabbed panel stack mod with buttons instead of the tabs?
Then you could use something like this:
$imagebutton(0,0,50,20,<Path>,<MousehoverPath>,COMMAND:View/Tabbed Panel Stack mod/Select tab/Panel No.0 Cycle Backward;REFRESH,,)
$imagebutton(50,0,50,20,<Path>,<MousehoverPath>,COMMAND:View/Tabbed Panel Stack mod/Select tab/Panel No.0 Cycle Forward;REFRESH,,)
$imagebutton(100,0,50,20,<Path>,<MousehoverPath>,COMMAND:View/Tabbed Panel Stack mod/Show/Hide tab/Panel No.0;REFRESH,,)
This would give you three buttons. The first two are switching the tabs forward/backward, the last button activates tabs if needed (useful if you have many tabs inserted, because its easier to choose one of them instead of switching with the forward/backward buttons).
Or if you want to choose the tabs directly with buttons, use:
$imagebutton(0,0,50,20,<Path>,<MousehoverPath>,COMMAND:View/Tabbed Panel Stack mod/Select tab/Item properties;REFRESH,,)
$imagebutton(50,0,50,20,<Path>,<MousehoverPath>,COMMAND:View/Tabbed Panel Stack mod/Select tab/Artwork view;REFRESH,,)
Or did i misunderstood you?
EDIT:
Could you describe more precisely what's your goal?
Maybe there is another solution than using trackinfo mod.
