I honestly think you should look at the database just like any other piece of your code, you cannot just replace GTK with WX Widgets and except there to be no migration work. And most of these differences between databases have nothing to do with SQL, but rather databases not implementing it correctly for legacy reasons. I would not expect a new database query language or NoSQL databases to do this better.
