I suggest you take a look at a very interesting read.

Once you're done you should consider reading the docs, especially the tutorials and examples.

Then you may consider trying out the forum search function.

If you do that you might be able to :

  1. figure out that none is going to do your work for you
  2. rephrase your question/problem in a way that allows us to answer it and prevents advanced users from dismissing your thread
  3. find the answer on your own (turns out drag and drop is well documented and there is at least one board game available in the Qt software section making use of it in the way you're interested in)

Please don't take this personnaly though. It is part of an attempt to educate new users. Only time will tell if this a reasonnable goal.
