detect website in focus and send to a remote server

Hi Freelancers, I need a piece of windows software that runs from within a notification icon (or u can offer other solutions as well, but it must be easily accesable for ursers) and perform following task : * it will only works when an internet browser is open * when the user opens our program by pressing the notification icon , and gives the instruction to send the URL -> the software send which url was open in front of the user to a server (SQL or MYSQL). The software must be able to detect the focus of the TAB within these 3 internet browsers : firefox, ie and chrome and retrieve the url from , and will only send the URL which was in focus. * The user will have a database login stored on his pc for the database. This info will be stored into the database : 1) username 2) time and datum the user wanted to save the URL to our database 3) the URL visible at the time the user click our notification icon This discription is only a basic idea, the software have more features, but those will be revealed once a coorperation starts. The only thing i'm worry about is the notification icon, when we press on our icon a dialog will popup and the focus of the internet browser will be gone.. we need to know the url the user was looking at when he pressed the notification icon, when u can detect this the moment he clicks our notification icon then i see no problems. i want a quote for this basic software first : a) create software that runs from notification (or give another idea for easy acces) b) when the user click 'check URL' button, the dialog will will show the latest URL the user was watching . When there was no internet browser open at that time it shows 'No URL' Thank u
