[Glade-users] How to create a popup window

I draw a simple application in Glade with a main window and a button.
With the builder I show the GUI and all works fine.

Now I need to show a popup window when I press a button on the main 
window and it seems to me I have two way to get it.
The first one is to create and show a new window in the button_pressed 
callback and destroy it in the delete-event callback of the new popup 
window. In this case I don't use Glade to create the popup window and I 
have to manage all the properties and signals via code. The window is 
created from scratch and destroyed when its works is done.
The second one is to draw the popup window and set all its properties 
and signals in Glade, use the builder to create both the main and the 
popup windows, show just the main window and in the button_pressed 
callback show the popup window and hide it its delete-event callback. 
The popup window will always exist even if it could be never used.

A few questions:
is my analysis right?
Is one way better than the other?
Is the second one more resource demanding?
