Continuing from my earlier circuit to connect external LEDs to the pre-loaded program, here I connected external push buttons to control the LEDS on Tiva. 

Connections are:
1. GND Pin to GND Rail on the Bread Board (Green wire in the picture)
2. One wire from GND rail to one side of the button (White). Do the same with the other button as well.
3. PF4 and  PF0 are the button input pins on Tiva. So Connect one wire from PF4 to other side of button 1 ( blue/black wire). Connect another wire from PF0 to the other side of Button 2.(red wire) 

You are good to go. Now if you press the buttons on the bread board, you should see the same functionality as the buttons on the Tiva Launchpad.

Remember that this circuit works only with the pre-loaded quick start RGB on the Tiva TM4C123GXL launchpad. This is just to do some experiments with the board while I wait for the Edx Embedded systems shape the world MOOC course to start.
