Help needed with community translating platform

[jjmoncur]

Aloha,

I need help figuring out how to build a platform to do online translation. I basically need a split screen set up where one side can house an image (Page of english text that's been scanned in) while the opposite side can be used to enter the native language translation. There has to be a save button for the new native language translation that's linked to a database. Unfortunately I'm pretty clueless on how to do this so any advice or help I could get would be amazing. We're trying to provide native language children's books for kids in the marshall islands and this is a huge part of the process.
here are some examples of what I'm thinking of:

Again, any help would be amazing!!! Thank you.
