Separate web app for List new orders

Hi all, I am developing a Woocommerse site for a Pizza shop. So the shop will get around 10 orders per hour so, my client do not prefer like go to Woocommerce order page and click the order and print the delivery-notes each time.
So I need to develop a simple web application which needs to run on a subdomain where i want to list all orders from Woocommerce. When the new order comes to woocommerce, then this web app to make a sound and highlight the new order on top. Also there will be a simple print button on order table.
I knew this all can be done in Woocommerce through plugins but my client prefers a simple interface to list orders.
My question is, can I develop this simple web app using SpringBoot through Woocommerce REST API, if so, how to implement this. Your suggestions will be appreciated.

Thank you
