If I can build a work log on my desktop: I can build a work-log on the internet
If I can build an employee database: I can build an employee database on the internet.
The unicorn of access on the web doesn't quite exist yet I am afraid.
BUT
I think your closest match is either a hosted PHP Application generator or a hosted ASP.NET application generator
Whatever you do you will need to spend money on a web host.
The minimum this is likely to cost you is in the region of $15 a month. If you don't want to spend the next 6 months learning about the insides and outsides of frameworks then I would suggest you go to one of the below three providers who all provide complete environments set up and ready to go with their particular generators pre-installed. This is good value you cannot beat these guys on cloud hosting costs and unless you are very advanced and have very particular requirements its a waste of time to try.
I have a cloud hosted provision with Nubuilder Pro - I pay a monthly amount and I can create as many applications as I can fit within my space ( which is more than I can use even on the lowest version ). There are a number of providers that do this. With nubuilder the software is free. With other providers the software that helps manage the construction of the site (like access on the web is not free) Whatever you go for you will need a webserver. Paying one of the guys below means they set up the environment for you. Which is a BIG step forward.
Be warned n-tier web applications do not play as friendly as the desktop you WILL be slower to construct applications than you are on the desktop, getting into it WILL take time and a bit of commitment, you WILL have far less flexibility regards coding, there WILL be less people about to ask questions and there is far far less WYSWIG design capabilities, error trapping is poor and errors are far more likely to be fatal and the really big warning is that on release of new web frameworks you may not necessarily be able to update without a full site re-design (A fact that comes as a nasty surprise to many CIOs and Project Managers when they realise that they are locked into front end system replacements every 4 or 5 years ) Know how to get data to your local environment out of the back end and accept that the front end is ephemeral and not likely to last in the same way as your desktop applications. (Your database will last but don't expect to be running it through the same front end ten years from now)
That said the design of these items is significantly faster than its ever been.
Scriptcase and PHPRunner have free downloads that are good for getting started.
Commit to one and go for it. - I've gone the php route. Nubuilder only connects to MySQL whereas Scriptcase and PHPRunner connect to pretty much any database. I started with Nubuilder and probably will use Scriptcase as well because importantly it connects to anything and the design options are more polished. It is actually not quite as conceptually elegant as Nubuilder which despite its rather drab looks is incredibly flexible. I would probably be able to change it s look if I was prepared to get my own server and install everything on it myself. That is not something I have time to do at present.
Nubuilder and Scriptcase have web design facility so you actually design them through a web page. PHP Runner is more traditional in that you have a program running on a desktop and then you publish your application up to the web server.
Zoho Creator / Alpha 5 hold your hand even more but as a result are even more proprietary and fantastically expensive
