samsung galaxy s 4 - How to create a hardware shortcuts in Android 4.3?

I have Samsung Galaxy S4 GT-i9500 running the latest firmware with Android 4.3.

I want to create "hardware shortcuts".

For example, if I hold volume up and home at the same time, then it'll open an application that I set, for example "Firefox".

As a Linux user, I know it's possible in Fedora and Ubuntu.

Is it possible with Android? My device has not been rooted.
