Simple IE & Firefox Toolbar That Searches a Website

I need a simple toolbar that can be installed in both IE and Firefox. The only thing it needs to have is a search box and submit button. The search will simply redirect to a search on one of my websites. For example: if someone searches "my search" and presses enter, it will go to a URL similar to this one: [login to view URL] Besides this, the only requirement I need is that it should be installable via an .exe installer (both Firefox and IE). The reason is because I will eventually integrate it with a 3rd party installer. It does not matter what language it is coded in, as long as it works. Please PM me with any questions.
