Google App Script can be used to do things like send email based on information in a Google Docs spreadsheet or MySQL database, collect and analyze submission forms, or track stock prices over time. To help potential script programmers get started, Google offers several script templates that do things like generate personalized driving directions and a Google Map for inclusion in an email.
Google App Script is even up to the task of creating full-fledged web apps. Google engineer Dave Abouav, who teach physics part time at De Anza Community College, used App Script to make Flubaroo, a tool that leverages Google Forms to allow teachers to administer quizzes and assignments with automated grading.
Google App Script includes a UI service, in the form of the UiApp class. The API class provides a mechanism for generating web user interfaces, which make it easier to interact with scripted processes.
But creating a graphic interface using code can be a difficult process, because it's hard to visualize the end result. So Google has introduced Apps Script GUI Builder, which allows script authors to assemble a graphic user interface by dragging and dropping graphic elements.
"The GUI Builder lets you construct user interfaces for your scripts quickly and easily," explained Google software engineer Corey Goldfeder in a blog post. "Simply draw the application, set some properties, and you are ready to go!"
To start using GUI Builder, open the Script Editor--accessible from the Tools menu of a Google spreadsheet--and select "Build a user interface" from the Script Editor's File menu.
After building your GUI and app, you can make it available as a web service by selecting "Publish as Service" from the Share menu in the script editor. This creates a URL for the app and loads the GUI. The GUI can also be presented inside a spreadsheet or on a Google Sites page.
