Creating Payments using our coin


I am considering using the cosmos to do the following:

a) Create a coin
b) Be able to store it in a wallet such as cosmostation
c) Being able to use it like a means to pay on my ecommerce website.

Similar to how metamask is used for purchasing NFTs on OpenSea. I want people to be able to use the Cosmostation wallet to purchase items on my website using my own currency.

I am going through the SDK for cosmos but it has a lot of different articles on several topics. Would appreciate if someone can point me in the right direction on what to read up so that I dont go off into the wrong directions in order to achieve this.

Thankyou in advance
