Thanks to '''James Henstridge''' and for his wonderful work on libglade which makes it easier to store the UI widget information and it's actions in xml file called GLADE. Using libglade will not only save the time of development but also makes the Marbles-output as platform independent. We can share the glade file for UI over network and recreate or edit the current glade file to make it more complex. It gives an option for children to play with it.
I have also made a design without libglade library using database storage but after getting suggestions from sugar members, I removed that in my technical approach. Whole design is thus made very simple. Mentors can read that approach in my original GSOC proposal submitted to google.

Libglade is a library designed to dynamically load a user interface from an XML file on disk. These UI description files can be created using the Glade UI builder. It provides several options for connecting callbacks up to the interface including an `autoconnect' option that scans the program's symbol table for callback functions.

Post-building activities like activity creation from python source code, sharing source code using xo bundle can be done later.
