First, maybe this got misplaced? It doesn't sound like a View or Layout issue?
But anyway, can you explain more about what you want your application to do? Is it just that it starts up, on demand from the user, checks some things and launches that new application?
Is it that it runs in the background like a daemon and starts applications based on some data it collects?
Is it a menu that fires up other applications?
Is it that it coordinates a bunch of smaller applications?
So yes, I think more information would allow us to better answer the question. =)
