C# - good quality debugger, GUI interface. I like windows forms, easy to do simple GUI, which is all the GUI I do. IF you want fancy stuff you probably need to use the WPF. In C# I use Entity Framework to interact with the DB. If you are doing this, just for yourself, I found SQLIte DB to be wonderfully easy to use. The DB is a library, not a separate application opening up ports for the world to abuse, and the DB is stored in a simple file.
