Gini App Builder is a graphical WYSIWYG tool to help you quickly build simple apps. It's similar to Hypercard or Microsoft Access. There's an underlying database, but you don't need to know any database programming to use it. You can simply drag and drop components like forms fields and buttons to make a site or app, where people can input data. You can then look at this data and use it to do something else or present new actions to the user.
In a way, it would be similar to this Google form itself, but you would have more control over the design and access to more powerful functions like search.
