I am new GUIs and tried Perl/tk in HP UX environment, so I created little GUI and there are some buttons to call shell scripts, tcl, perl scripts. it is OK so far, only problem when I click on button the GUI dissapears, not remains to re-use.
code clause:

$window->title("UNIX Test World");
$window->configure(-background=>'#D2B48C');

$window->Label(-text => "PNM ServisNET Toolbar", -font=> "Helvetica -14 bold", -
background=> "#D2B48C")->pack;

$window->Button(-text => "IDLE Users for 5 Hours! ", -command => \&action1,)->pack;

MainLoop();


sub action1 {
 exec "/aydin/idles\n";
       }


exec replaces the perl program with whatever program you run. But not knowing what you are doing all I can suggest is look into open() or IPC::Cmd or IPC:pen2 or IPC:pen3 or maybe Tk (which I have no experience with) has functions/methods builtin that you can use.

You may also want to run the command in backquotes - so that the result of running it gets returned into a variable which you can then process as you wish.

As Kevin says, exec replaces your existing program, so is indeed going to get rid of the GUI!

I solved my problem by replacing "exec" with "system". Thanks for your help.
