If you’re currently using absolute sizes, the button’s won’t appear where you might want them.

You might want to make them just take up a percentage of the screen, and use Screen.width/Screen.height when creating them.

Rect brush = new Rect(0, 0, Screen.width * .5f, Screen.height * .1f);
if (GUI.Button(brush, "This button takes up half the screen's width.")) {
    //Do whatever
}

Then you can make buttons at any part of the screen:

//Make a rect in the middle center of the screen:
Rect rect = new Rect(Screen.width * .333f,
    Screen.height *.333f, 
    Screen.width * .333f,
    Screen.height * .333f);
GUI.Box(rect, "This is in the middle of the screen");
