How to create signals and slots system in C++?

Question

[Holy moly my first question here :D]

Currently I'm working with SFML library to create full GUI system. I've been checking my options on how to handle events, so I thought that Signals and Slots would be pretty good idea (like in Qt).
And here I encountered problem, I have no clue where to start... Does anyone have some source which may prove useful? Or/and write a description on how such system works.

Thanks!
