Running an executable file from a user created interface

My project deals with accessing ntfs partitions in linux using an interface. I have created an interface using Glade. But the problem is i dont know how to provide a link from the interface for executing the programs. Is this possible. I am new to programming in linux please try to help me as soon as possible.
Thank You.

Your program should simply be able to read() the mounted ntfs filesystem, just as it would do so for any other part of the file system. Do you have some particular application that you want to launch, which performs ntfs-specific work? If so, you will probably need to use fork()/exec()/wait(). See the man pages for these system calls, and if you have more specific questions about these, come back here to ask.

I have the programs that are needed to perform the operations on ntfs partitions. i intend to execute these programs using the buttons that i have created in my interface. for eg. if i click a button named NTFSDIR it should execute the program ntfsdir which displays the contents of the partition.

Okay then, in your event handler code for the button(s) or other widgets, you will need to fork() a new process, launch the requisite application(s) using one of the exec() family of system calls, and then wait() for the process to complete. Consult your local man pages for the details on these functions.
