Please be aware, Augusto, that Rick is known to be a bit... OTT. Don't
take him too seriously (but he's not an idiot either).

Possible? Yes.
It'll be well'ard to get much done with too limited a knowledge base,

Neil Cerutti suggested Tkinter. Choosing a good simple GUI toolkit is
a good idea over Pygame for something like this.
I've used Pygame and I guarantee you it's not the hammer you want.

(I don't know much about GUI's to be honest, though.)

In regards to this, I really would recommend just taking Rick's
suggestion: Tkinter; canvas; menu; etc.


Now, as I'm probably the most new programmer here I'll point out that
I don't agree with Chris when he says that:

As a new programmer, you will throw away code whether or not you
practice beforehand. Beware of that. If anything, it's the best thing
you can do*.

Other than that, he's spot on. Personally, I'd start on the big
project sooner rather than later, but not be afraid to dump all the
code every now and again.

*Anecdote time; a friend of mine who learned VB as his first language
wrote as one of his earlier scripts a 2075 line program with no
indentation - I still have a copy of that gem tucked away in a very
dark corner.


Last point; DRY. Look it up and breathe it. People might wonder why
I'm making that big a deal about it (it's not the be-all and end-all
of anything) but as a new programmer most of your random bits of
not-nice-looking code will probably just be a breach of DRY. If you've
written the same thing 5 times you've *probably* done it in a not-too
efficient manner and the real solution will be the next ladder up in
the hierarchy of programming.

As someone new, paying a fair bit of attention to this will probably
make what you learn some important higher-level concepts faster.


Best of luck, I hope I added something helpful.
