GUI screens using BPM/BRM

Hello All,

I am new to BRM technology and my question might be very basic, but i was just wondering is it possible to develop UI screens using BRM/BPM?

I have a requirement where from a UI screen, user will push the data to external system. Once user perform certain action on the screen, in the background i need to fetch data from SAP system and using PI interface send the same to external system(to vendor)

Thanks
