Which software will help me better to develop web application?

Answer 1

If you are talking about HTML CSS or php then there is no such software.
But there is just a note pad (or notepad++) to write your code.
For creating a host on your computer and to create databases you may install WAMP (for windows users) or LAMP (for Linux users)
