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.

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 )
