Need some advice?

I want to build a simple Dashboard that will allow the user to input run length time and stop length times.

All times will be in munits.
Example the run length time might be 165 minutes, stop length time could be 45 minutes.

Then use would just press start button,

What would be the best way to go about this, Software?

Do you know about the node red dashboard nodes? Use Manage Palette to install node-red-dashboard. It sounds as if you want two numeric input dashboard nodes, and a Button. Or perhaps better would be to use the dashboard form node.
