how to build something conceptional quick

Can someone help me to spin some ideas. I would like to build an app and use it only in the Google Chrome browser for practical reasons.

I want to make some helper app for renovation off a hotel complex. Basicly, there is a main contractor and a subcontractor. Every room needs to be renovated by the subcontactor wich consists of a couple of tasks for every room to be completed. During the day, the main contractor makes an inspection off the rooms wich are completed and if there is an issue he should be able to make a simple note and send it to the head of the crew doing the renovations.

I want to make a gui of cubes with room numbers of every room and then by tapping t the person could make a simple note in a sketchy way or typing it. and the sending it.

Can someone assist in giving advice about javascript libraries that could be used, wireframing it, experience with using the google browser app as a way to deploy an app. How to quicly get a nice user interface. Has anybody seen something like this already? I am looking for a way to use tools/components that can be combined to create a functional app.

I hope I am not asking too much so anything is appreciated

Thanks
