By inheriting from SerializedEditorWindow instead of EditorWindow, you can make Unity editor windows in exactly the same way you make inspectors: by using only attributes.

SerializedEditorWindow.cs

/**
 * 
 * Inherit from SerializedEditorWindow, then mark field as [SerializeField] will make them appear in the window
 * 
 * If you want to add some button, you can override OnGUI()
 * 
 * Inspired by the OdinEditorWindow
