I can develop C# application for you. There is form with text field, button(Execute Query) and button(Export Result) . You can write query on text field and can see result in grid after clicking on 'Execute Query' button
And you can also export result into csv after clicking on "Export Result" button
I will use
1. C#
2. Google APIs Client Library for .NET
