Submit a form without keyboard input, addition with the help of button

I am new to WordPress. I want to create sales status website, something like this...

< - button>Item 1< + button> < - button>Item 2< + button> < - button>Item 3< + button> < - button>Item 4< + button> I want a plus and minus button to add the number of a particular item.

For example if I sold (item 1) 4 times, I will click it 4 times and the number will show at the bottom.

Do I need to use a form plugin for this
