WPF app skeleton

I need a very simple, low-academic level WPF application skeleton (all "backend" job is done and this app will provide a UI to the functions. It will utilize two DataGrids (left-side and right-side), a dropdown, two buttons, input box and appearing input box. The app has to be functional rather than great looking so no big design skills or huge experience is needed, but the code must be maintainable. A dropdown has two options, switching between them will change some columns of the data in DataGrids. All data shown in DataGrids can be mocked as any objects of class containing few numbers and strings. Number of columns in each DataGrid will change between those two options. Few necessary functionalities: * Reading a list of mocked objects to a both DataGrids, * Refreshing DataGrid once in a while (re-reading data from list), * When a row in left-hand DataGrid is right-clicked, it should open a small input box (or utilize existing) to provide a number and then after clicking enter carry this row (with additional column indicating provided number) to the other DataGrid, * The first from top button visible in mockup can be a dummy, * The second from top button visible in mockup should trigger trivial parsing of data in inputBox (split by space and cast to strings or numbers) and insert it to right-hand DataGrid. Attached file contains a simple mockup showing the design. Timeframe: I want it done by 20.00 GMT 24 July. I will answer any questions and favorize quick iterations. If eas
