as you can change the graph of the arduino ide?

as you can change, the graph of the arduino ide?
for example, add a button, resize, add a tab, etc..

I understand that the ide, is based on Processing,
but as ide in charge of this program so that it can change?

The source code for the IDE is available on the Arduino web site. You can download the source code, make whatever changes you like, and compile, link, and run your version, instead of the official one.

Thanks

do not understand how it is compiled for windows, or Modific the ide

Well, it can be done, and you have access to the tools and resources needed to do it. Whether you're capable of doing it is another matter - Arduino is not designed with the intention of supporting people who do that sort of thing so it would be up to you to figure out how to do it. There's nothing stopping you, but don't expect it to be easy.
