Dark Basic (V1 and referred to as 'Classic') as well as Dark Basic Professional (V2, Classic's updated and bigger brother) are programming languages - like C++, Forth, Pascal or any other you'd care to name.
But, they are essentially DirectX wrappers based on the BASIC syntax allowing easy access to Microsoft's 3D engine. If you already have a working knowledge of programming in C++ then Gark GDK is an 'add-on' for that which gives you the same functionality without the tiresome DirectX programming side.
As already been said, FPSC is really the only program which will let you produce games with little or no programming experience. For the rest, you will just have to get stuck in and learn how to do it the hard way - like we all had to do!
Most of the other programs are simply tools to help you write games.
For example, you can load 3D models into Dark Basic, animate them and so on, but you need a program with which to create them. You can use ANY program (including Poser), providing you can export the model (or convert with a utility) to a format compatible with DB.
As a rule, if you can get a model into .X or DBO format then you can use it in DB (DBC also supports 3DS).
If you want to learn to program with DB from scratch, may I suggest you start here:

If I understand what you are saying correctly, it's simply doing as you told it to. If you aren't using a never-ending loop, your program ends when it's done everything. Add a
Wait Key as the last line and it won't close until you press a key.
Get stuck into the tutorials and it will soon fall in to place. Unfortunately this won't happen overnight though...
