I't works fine as an entry but I can't figure out how to make it to the sidebar, I can't find a way to do it with a .php file or a simple vertical banner inside the sidebar, do I have to edit the template or there's any other way?
Well yes, to display something on any page you'd have to edit the templates. the file you have to edit may vary with which theme you use and which position on the screen you want to put your code.
Thinking of this, it might actually be easier to write an extension for what you want to do, and then just use the [[ myextension ]] Smarty tag in your templates (assuming your extension is called 'myextension').
