It's important to design your application correctly - don't just start writing code and hope that it will all come out in the wash as that's one sure way to waste a great deal of time. Start by thinking about what your inputs are, what outputs you need to produce, on what data is available to you and what you need to store, and how you can get from "i" for input to "o" for output. For experienced programmers, this may be second nature but for newcomers, it isn't. As well as training notes on PHP, Perl, Java and other languages, we also have notes that cover the elementary principles of program design and notes that cover the concepts of object orientation, which we use as appropriate on our courses. We often find - with Tcl/Tk in particular - that newcomers to the language haven't got prior experience in another programming language, and so we're happy to tutor them from first principles, and using a minimum of jargon.
