How to add product in woocommerce with php code

Hi,
I have a wordpress site. There I installed woocommerce and that’s amazing .
I just want to create a new page for adding new products instead of existing “product adding page” of the wordpress .In that page, all product categories are displaying. Whenever I will click on a category, i want to get the page for that specific product with other options . After submitting the product, that product should be stored into the mysql database . that’s all .

Thank you .
