How to integrate all software in a PC?

Question

It seems that only online programs are interrelated and work together .. so to incorporate a new program it must be a child of a strong parent program!
What if i want my self created program to be independent and a parent itself?
How do i incorporate them such that they can use system resources and also they themselves be used by system?
I have done this to some extent by creating links in : /usr/bin folder or even: /root/bin .. but although i notice progresses still i am not satisfied because ..

Answer 1

Let me explain by mentioning a very simple example;
In one of my programs i have created functions to react in an specific way .. when ever i enter a code .. for example if i entered hi the program outputs: hello
I have shared these programs so i expect all other programs to be aware of these functions .. unfortunately even the compiler g++ is not aware of them .. every time asking me to define or declare .. and worse than that the compiler doesn't know where /local/bin is .. let's skip about compiler because it is another discussion!
On the other side i see system programs search for finding answers in system related applications
I expect whenever i type and enter hi .. all programs react in the same way .. because this hi program is shared
In cases i see some suggestions done by system or programs which means that they know about shared apps
When i say on line i mean those processes which are shown in system activity table .. either active or slept! They react whenever something is related to them.. but in case of my own programs which nearly all of them have functions such as: autoStart or auto_start or autorun .. they never start automatically unless i add them to autstart folder which is related to kde .. although recently even this option is not useful in case of some of them ..
Generally my self-made programs are not supported voluntarily .. unless i force them in by entering direct commands..
I am not sure if i have explained clearly!

Answer 2

I said in my other post that i failed inserting my programs into kernel ..
To keep and enhance integrity i will not use or create conflicting programs ..
Suppose you are teaching your child you should not say :
apple is apple
and the other day say:
apple is banana
You know what happens if you do so!
