our project is to develop a parallel program which can search documents (*.txt files) from a large document collection matching with query requirements. Now, we have finished the search engine program using C++ and MPI on Linux. We compiled and tested the program in command line mode.

 To complete the project, we need to create a interface for the
search engine program in Linux box so that the system can accept query words and display query results in a user friendly fashion (a window interface, in which users can simly click on a button to submit his querys, and see the results displayed in a table. A doucment shown in a row of the table can be opened when users click on that row). 

We do not have any experiences with this. We do not know which computer language is best suitable to our case. Can anyone please share your experiences with us, or provide some helpful advices.

To me, this sounds very much like a web interface. You need
a web 
server and knowledge of some scripting language (PHP, Perl,
Python, 
Ruby, Java, etc.) or even a compiled application that can
interface 
with your MPI program and can take HTML queries and produce
HTML 
output. The interaction with the MPI program can simply be
done via 
its standard input/output - this way the MPI program is a
completely 
separate entity from the script/program that does the HTML
part, so 
you wouldn't have to think about linking f.e. graphical
libraries in 
the MPI program and synchronization issues.
