Will a old computer with 1024M of RAM and a Pentium 4 CPU be able to host a personal website, while still allowing me to use the web browser? Does someone have any recommendations for helping it run more responsively?

It will probably work, but might not be as fast as you want it to be. Fool-proof way to find out is to try it. :) – colboynik Feb 14 '14 at 05:31

Potentially. With only 1GB of RAM given it's going to have a graphical interface, using a web browser (which are quite memory-heavy nowadays), the experience may be lackluster.
I would suggest using a lightweight desktop environment instead of Ubuntu's default Unity, such as Xfce or LXDE. You can install one of these from the command line on Ubuntu Server using sudo apt-get install xubuntu-desktop
or sudo apt-get install lubuntu-desktop
. That way, your desktop/web browsing experience leaves as much RAM as possible aside for the web server to use.

Running a web server with this configuration is possible just use add classic gnome environment by following these simple steps:
- open the terminal window.
- sudo apt-get install gnome-panel
- Now logout and change the default unity environment to gnome with the option above(left) the username bar.
Personally I have the same configuration and its working good classic-gnome.

My recommendations:
- Don't use the server to do anything else than hosting the website (don't install any desktop enviroment, a server is a server)
- Don't use ubuntu on servers, especially on servers like your server, go for Debian instead.
- Don't install Apache, use Nginx instead.
If you really need to install a web browser, then download one of these, no desktop environment needed. If you really want a GUI experience then go for Openbox
