Yes it is possible. You can add a Panel "StartProgram" or a Button "StartProgram" (click on + General and choose StartProgram). You must then enter Android Program name of the App you want to run (e.g. de.mdiener.rain.usa). Program name can be found in URL of App on Google play (e.g. https://play.google.com/store/apps/details?id=de.mdiener.rain.usa).
