Hi,
I'm building a popup window that has a Gtk::Grid inside it. The first row
has a form with three Gtk::Entry and a button to add the information to the
program. The rest of the rows has the items created before in that way
(just with Gtk::Label) and a button to remove the information. Like
I'm not experienced but here's a quick idea:
Create a new derived Button class which handles its own click by
overriding the virtual method, and in that method it emits a signal
which passes the button ID/row number as a parameter. Then listen to
this signal from all buttons :-)

(a) by passing something that identifies the button within user_data
when you do g_signal_connect...
(b) using something along the lines of
Thank you all guys, you're incredible! :)
I've finally implemented the Jon Zabala's answer, I think it's the easiest.
