I am looking an open source application. Application should have :

  * database support ( create two or three table )

  * GUI ( what I have created should be seen )            

Example :

Assume that I have created a table ;



       X_table  :          |  A  | B  | C | D |



 After creating  table, I am loading data 

                           |  A  |  B   | C  | D  |

                           |  1  |  11  | b  | f  |   -

                           |  3  |  12  | a  | o  |   - data 

                           |  4  |  13  | r  | o  |   -



    When I am opening application not for loading data, I want see data in graphical 

 interface.



   One day, I want modify existing data. I can just clicking the place then add new 

 data



    Assume I want change 12. I am clicking that position and then writing new data

                           |  A  |  B   | C  | D  |

                           |  -  |  --  | -  | -  |   -

                           |  3  |  19  | a  | o  |   - data 

                           |  -  |  --  | -  | -  |   -

Are there any open source application which have above feature ?

Application can be so simple,

 * no internet connection

 * support only one database 

 * static table creation ( once created never changed )

Application can be run Ubuntu 12.04 and/or Windows.

In other words, I am wanting database viewer and editor.

EDIT:

I should load pdf file, image etc. or give path of the file to the application.

This link can be reference to my question . ( Interface should be like this, just a list )
