RF push button (transmitter) to activate LM35 temperature sensor (receiver). Can you give me syntax to write the code for transmitter and receiver section?

You have a lot going on here.
1) You have an Rf transmitter. You can either buy a complete module or build something with a PIC.
2) you have a matching receiver which will do something in response to the signal from the transmitter.
3) You have a LM35 which is an analog temperature sensor, not a radio receiver, and it is not clear what you want to do with the temperature information.

We can't help you much without a lot more information.

If I press the button in the transmitter, it should either disable/enable LM35 to read temp and convert it to turn dc motor (at the receiver). How do I program the PIC16F876 microcontroller for this action?

Start by dividing the problem into several parts. I suggest these:

1) Find a radio transmitter and receiver pair.
2) Write a program that will run the motor when the receiver gets a signal from the transmitter.
3) Write a program that reads the LM34 and runs the motor when it gets hot, and shuts off when it gets cool.
4) Combine these three parts to get the behavior you want.

Each of these may be a challenge if you have never done things like this before.
