I am wondering is there a possibility that every time I logged in to my Ubuntu, the desktop is set to Gnome Classic (no effect)? It is too redundant to set and choose it in the login every time.

The login screen always uses a user's last successfully logged-in session type as the default. If you don't change it, it logs in to the same interface you used before.

If that is not happening, that should be reported as a bug (see also this question). The affected package is lightdm (as LightDM provides the login screen in Ubuntu 12.04).

If the problem is that GNOME Classic is not installed, install the gnome-session-fallback Install gnome-session-fallback package. In particular, if the problem is that you are selecting Ubuntu 2D as the session type and you get something that looks like Unity, that's normal--Unity and Unity 2D (provided by the Ubuntu and Ubuntu 2D session types, respectively) look very similar and both have launchers instead of a bottom panel containing a window list.

Whether or not this is due to a bug, it is also possible to set the default session type manually, as explained here. (However, if you're experiencing a bug, that also might or might not work. It would be valuable information for the bug report though, for you to indicate whether or not it does, so I recommend trying the techniques there.)

If you are trying to run gnome-panel in Unity or Unity 2D (as you asked about here), that will not be run automatically unless you configure your session to do so. gnome-panel is like any other program; to make it start automatically, use an appropriate method here. Or follow the specific instructions for adding gnome-panel to your startup applications, that Seth has added to his answer.
