I want to start making my first software please help me..

Question

Help me

Answer 1

Step 1: Learn a programming language
Step 2: Download an IDE (or a text editor, a compiler/interpretor/browser, and (optionally) a debugger on *nix systems)
Step 3: Start coding.

Alternatively, you can code in this app's code playground.

Answer 2

First you should take some theoretical steps:
+ Decide what the software is for?
+ Decide what the software should be able to do
+ Decide on which plattforms the software should be runnable (Android/OS/Windows/Linux /Web)

Then learn the language you need.
Afterwards plan which objects, methods are needed. Is a server needed?

After analyzing use-cases and object-methode relations, start implementing the sofzware.

Good luck.
