Kill specific terminal using shell/bash

Hello elite shell/bash specialists,

I have done plenty of STFW and some RTFM, but I cannot find a clear solution to my challenge

Goal:
My goal is to have a script(of any language, preferably shell/bash/anything that can run things on unix), which will kill specific unix terminal windows for me. Killing just the process itself does not satisfy my case requirements and nor does killing terminal on process end. Also running everything in one terminal is not the case.

Background:
I am working on a massive scale db-plugin tester. It spawns 2 new terminals per each db - one for db and one for app(app needs db specific settings) it's tested against. There is 35 dbs in the collection and therefore I am in danger of having 70 terminals hanging on my screen. The spawned terminals cannot automatically shutdown on process end - in case an error occurs and debugging will need to take place(those terminals contain vital logs). After my tester is done with one db and everything ends happily, it should proceed to the next db. It would be very useful if it could dispose of all the terminals that are no longer needed when it proceeds to the next db. In fact, I believe it is vital to be able to do it.

Details:
The command I use to spawn each new process looks like this:
Code:
gnome-terminal -x bash -c "sh app.sh; exec $SHELL"

Note there is plenty of shell commands before and after each spawn, i.e. init and cleanup operations

Any sort of clues is much appreciated. Also feel free to suggest any change in my design/code that could make my goal more realistic.

Thank you

@Update

Problem Solved!

Okay I finally have it figured out.

To all those with the same problem, look at
Code:
gnome-terminal --disable-factory

It spawns killable gnome-terminals with unique PIDs

NAME
open - start a program on a new virtual terminal (VT). SYNOPSIS
open [-c vtnumber] [-s] [-u] [-l] [-v] [--] command command_options DESCRIPTION
open will find the first available VT, and run on it the given command with the given command options, standard input, output and error are directed to that terminal. The current search path ($PATH) is used to find the requested command. If no command is specified then the envi- ronment variable $SHELL is used. OPTIONS -c vtnumber Use the given VT number and not the first available. Note you must have write access to the supplied VT for this to work. -s Switch to the new VT when starting the command. The VT of the new command will be made the new current VT. -u Figure out the owner of the current VT, and run login as that user. Suitable to be called by init. Shouldn't be used with -c or -l. -l Make the command a login shell. A - is prepended to the name of the command to be executed. -v Be a bit more verbose. -w wait for command to complete. If -w and -s are used together then open will switch back to the controlling terminal when the command completes. -- end of options to open. NOTE
If open is compiled with a POSIX (Gnu) getopt() and you wish to set options to the command to be run, then you must supply the end of options -- flag before the command. EXAMPLES
open can be used to start a shell on the next free VT, by using the command: open bash To start the shell as a login shell, use: open -l bash To get a long listing you must supply the -- separator: open -- ls -l SEE ALSO
