You could theoretically create a database editor without any code. Drop a database connection component, connect a datasource to it (which defines table name), create a "scrollable box" and drop a text edit for every field, drop a few buttons and give them special functions like "save" and "cancel", and you should have an approximation of Microsoft Access form, but compileable to standalone binary.

I don't think anyone ever made projects purely in GUI though, there is always a need for some custom code to be written.
