Create a Toolbar

Overview -------- I need a Toolbar add-on for browsers that will work with FireFox, Internet explorer, Google Chrome, Safari etc. The toolbar should be an .exe file that a user can install onto there computer (It's easier for me to distribute in that format). Once the toolbar is downloaded and installed onto a users computer, it should then detect when the users opens a browser, then when the browser is opened.. check if the toolbar exsits. If NOT - Direct to a page where the user can install the toolbar. If it does - Go to the content page. The toolbar will be a simple iframe of a html page on my website, so you don't have to do any button or code programming, 26px in height and 100% wide, so I will be designing that. Your job is simply coding it to work perfectly on users computers, pc (mac at a later stage) and on all Operating Systems's. It should also have an option to set my site as the users homepage. I also need some sort of html code to detect if the toolbar has or has not been installed, if not it should re-direct to the download page, if it is already installed show the page content.
