Help for a newbie

I don't know if this is the right place to ask this but i'll try anyway.
I'm a computer science student who has recently finished college and i have one job i could do. It's about coding a simple program in order to make bills, print them, store them and get track of the customers too.
Problem is all i have coded (Java and C++) hasn't had a graphic interface.
In what language should i code it and what libraries/tutorials are good for people new to graphic interfaces.

My most heartily thanks in advance.

Looks like you may have bigger problems than just not having written a GUI before (which is by itself a bit baffling).

Don't you know that both Java and C++ have GUI toolkits? Especially Sepples.

Either way, Java has Swing (shitty pearl of wisdom, which took me long enough to realize: it's all about nested layouts, lots and lots of them) and C++ gives you a lot of choice, but Qt is a good toolkit for either learning or actual use.

But seriously, how come you haven't heard of them?!
