Summary

In this chapter, you worked through the first two phases of application development: understanding the problem and designing a solution. You learned how to develop an application specification by interviewing users and examining the data and requirements, created an optimal form layout for your users, and learned about the different types of widgets available in GUI frameworks for dealing with different kinds of input data. After creating the specification, you evaluated Tkinter to see if it was an appropriate technology. Most importantly, you learned that developing an application doesn't begin with code, but with research and planning.

In the next chapter, you'll create a basic implementation of your designs with Tkinter and Python. You'll learn about a new widget set, Ttk, and use it along with some Tkinter widgets we've already met to create the form and the application.
