Need help in programming

Hey there, I’m trying to make a project but I’m unable to program my Arduino UNO . Hence need help.
My project is Ultrasonic Frequency generator. In this project I’m interfacing a gsm 900a module with Arduino and a piezo electric speaker. what I’m trying to do is when I call the gsm number and give input 1 then a certain frequency should be generated. Same goes for other five inputs.
Help required asap.

Can you tell or show us what you have connected so far, and whether you’ve ever managed to upload code to your Arduino - even just the sample blink program?

Also, what deadline so you have when you say “asap”?
