To create a new GameObject that has a RectTransform (such as for use in UI), you should supply the RectTransform type in the second parameter, i.e.

new GameObject("GameObject", typeof(RectTransform));

This is particularly useful if extending Unity editor, such as through this menu item for creating a new GameObject as a sibling of the selection:

[MenuItem("GameObject/Create Sibling", false, 0)]  
static void CreateSibling()  
{  
    List<UnityEngine.Object> newSelection = new List<UnityEngine.Object>();  
    foreach (Transform selectedTransform in Selection.transforms)   
    {  
        GameObject newSibling;  
  
        if (selectedTransform.GetComponent<RectTransform>() != null)  
            newSibling = new GameObject("GameObject", typeof(RectTransform));  
        else  
            newSibling = new GameObject("GameObject");  
  
        Undo.RegisterCreatedObjectUndo(newSibling, "Create Sibling");  
  
        newSibling.transform.SetParent(selectedTransform.parent, false);  
        newSibling.transform.SetSiblingIndex(selectedTransform.GetSiblingIndex() + 1);  
  
        newSelection.Add(newSibling);  
    }  
    Selection.objects = newSelection.ToArray();  
}
