How can I make android IR remote app for external IR blaster with no programming experience ?

Simple answer: you can't.

You need a solid understanding of what you doing even when you use some of the game creation systems out there.

Since you did not specify any system I can tell you Android you can find good working apps for the purpose, similar for IOS.

With no programming experience, how do you plan to transfer the codes into optical informations or address the IR blaster?
