New to creating interfaces

Hello everyone,
I'm actually taking a course in data structures were I'm asked as a project to write a software which runs a small market
As the actual function of the software is easy to implement (using classes, lists, queues...), I would like to improve my interface and not use the black window were it is impossible to do something other than typing

What I was thinking is some interface which will help me to change the background, scroll down and select functions, select items, display bmps...

Could someone just give me a guidance to where I should start? If It's too hard to learn in a small amount of time, is there a place where I can download templates and modify them?

Thank you.

I tried to read the OpenGL tutorial on this site, but when I tried to copy the code in "Introduction to Windows Programming" I stumbled over 2 errors:

LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/test.exe : fatal error LNK1120: 1 unresolved externals

What are those? Thank you

Maybe you are not compiling with the right subsystem: If your "main" is called WinMain, then you need to use "/subsystem:windows", rather the (default) "/subsystem:console".
