I am not really in to web dev (let's say new to this field), but into system side programming(log parsing etc). Now that i need to build an web app which send emails by letting users enter/select custom fields from the UI , and can be used from web/tablet/mobile platforms.
Main goal of this app is to send emails. User will be logging in ( ldap/AD) , and then select custom fields, ( for ex: to, subject, type, priority, enter task details) and clicking send.
I was thinking to do this in HTML as frontend and PHP as backend. I know there are thousands of material out there at the internet, any pointers for these kind of application dev are really helpful. ( specially using these in tablets/mobile/web/cross browser).
