UNIX for Advanced & Expert Users

i am trying to develop a portal kind of thing where all the scripts will reside in unix.in our company we areusing Solaris.My requirement is to develop a portal which can be accessed from any where inside the oragnisation.If some one types a address 3.256.63.56/xxx.html the page should open.There should be many requests one user can put and for each request one button should be there.after pressing the button one shell script will run in unix and desired out put will be displayed.I have scripts developed in unix for all the stuff.only thing is to make it more interactive.i know a bit of html.how can i do this.the most imp thing is conncectivity between unix and the weblink.the restriction is i cant install any additional package in unix server.
