IT depends on what skin in particular. Apps is a button that I guess some skinners might use for different things. For instance, when you click the Apps button on either one of my skins - Brushed Blue or Brushed Orange - I have an Appmenu.skin that opens. That menu allows you to choose from Photos, cdrip, launchscreen, temps/sensors and such. clicking/touching one of those buttons will open whatever program. So, what skin are we talking about.
