The discussion centers on developing a GUI for a completed AC circuit analysis project on Intel Galileo using Arduino. The project is viewed as a significant learning opportunity, albeit a time-consuming one, with estimates suggesting it could take around 4000 hours. Two primary approaches to GUI development are proposed: the first involves studying GUI design literature, particularly focusing on open-source frameworks like X Windows, which may lead to conventional design outcomes; the second approach encourages a more experimental method without relying on existing literature, promoting deeper learning through trial and error. The conversation also touches on various GUI libraries, suggesting options like Tk and Qt, while questioning the compatibility of GTK with Arduino. The key decision for the developer is whether to prioritize the end result or the learning experience throughout the process.
