Brother,I had same views and after creating some small projects I directly tried to jump over large projects (went for data mining using neural network) and FAILED. I realized small things really matter. So I suggest just couple of GUI projects are not enough go for more. start with anything. here are couple of links I am staring with: 1. http://www.reddit.com/r/beginnerprojects 2. http://www.openbookproject.net/py4fun/
and there are many more you can go for "learnstreet.com" I am too a Intermediate but I prefer to say Beginner and if you want we can make projects together. I am Currently working on a small chat application. -- https://mail.python.org/mailman/listinfo/python-list
