Need help writing ccs c compiler program

So I have a school assignment due and I have no idea what to do.
1 –With help from a potentiometer to simulate a temperature sensor, the LED turns ON only when the temperature is above 70 and is Off otherwise.
2-Use a push button switch to turn the LED off for 5 seconds at any time.
3-Use the WDT (Watch dog timer) or the overflow of another timer to achieve the timing in step 2 (above).
If anyone can help with even just the 1st part I would appreciate it.
I am using a PIC 16F690

If you have the compiler, you have dozens of examples. Look in the examples directory. There are examples of reading a temperature, reading a keyboard, etc. etc..
You won't use the watchdog for the timing. It is too inaccurate on most PIC's, and just resets the chip. Just look at the delay function.

I did a search of the forum for likely programs, using these search terms:

first step

Cut code for a 1Hz LED program and get it working !
Until that's working do NOT attempt the real project....

After that look at the examples CCS provides.....
to program any computer, you need to think like one.. figure out the steps and sequence, get one section working then build upon that.

This is like my thread. But my thread is with a real temperature sensor and a display.
