Custom Menu at Specific Location

Hello guys,
I am new to Blender and I am creating my custom menu, to control my mesh and I found this tutorial .
There is explained how to create and append menu in Blender. But I would rather do is to create new Icon and window for this script in location showed in the image(Where red square is).

Is it possible to create menu at shown location? And if it is how can I do it?

Thanks for your answers and sorry for my mistakes I’m still learning how to speak English :slight_smile:

For a new menu there must be a new bl_context created. (sorry i don´t know how to or to explain that),
but you can include there buttons an dropdown menus into the original phyton script.
(right cklick = edit source = text editor)

It’s not possible:
