How to draw a field in a Plugin ?

Hi everybody.
I wanted to exepriment the creation of a plugin. I found the menu, created a Standalone Window plugin, that’s ok… But now ?
I’m searching a tutorial or just some clues about how to draw something in a plugin, and absolutely don’t find nothing…

Do you know tutorials or just methods to use to draw a simple int or text field (for example) in a Standalone Window ?

Thanks for any answer :slight_smile:
