I'm planning out a Raspberry Pi project, and I want to make it very easy to use. My dad will be using it, and I'd like for it to be usable without having to interact with the terminal. I just want a basic GUI that prompts for values to be input, processes them, and allows my program to act on them. I want the values to be repeatedly used, but easy to change when the conditions change, there's an error, etc. I thought the easiest way to do this would be a light weight Ubuntu app, but I may be wrong. Any suggestions?
To get started, here is a simple "Hello World"-tutorial:
Create a file
In addition, you can use the Qt Designer IDE which is available in the ubuntu repositories and offers some nice development features for GUIs.
