Create Raspberry 3 automation software and GUI

The software must be able to read the values of three load cells and operate three solenoid valves via relays.

The operation is as follows:

The user sets a target weight and actuates the solenoid valve that fills the container with liquid until it reaches the target weight and then turns the valve off.

All operations must be controlled by a 7" touch screen.

In the attached image you see an example of how the machine will look like.

Applications with generic text will not be considered, but please show that you have at least read the description.
