I have an idea for a website which I want to code entirely on my own. But the problem is that I have neither the skill nor the time required to learn languages like php and java which are required to improve the visual appeal of a website, and also make it dynamic and robust. In fact I don't think in my present situation I can't learn any language thoroughly except for HTML, which is of course, the most basic scripting language.
HTML, PHP and Java all perform very different functions. If all you want to do is display static information that you don't mind editing by hand then HTML is perfect. It's simple to learn and there are plenty of excellent resources out there to help you. If you need advanced features, such as creating a login system, allowing people to edit the content online, etc then you will need to use PHP to create that code.

I don't want my website to be "visually-appealing" - the primary intention is to get it loaded as fast as possible, and that's why I'm thinking of using only HTML and nothing else to build the site. The only concern I have is, will it be safe? Not many people will know about the site, but I'm planning to let some acquaintances at a reputed university to review the site, and they are capable of doing some mischief

HTML is infinitely safer than PHP. As HTML doesn't process any user-inputted information, there is no way HTML allows any form of hacking or malicious activity by your visitors. If you introduce PHP and start processing input from the user then you open up loads of security problems.

Actually I don't have to worry so much as it's an information site, pretty much like wikipedia but on a minuscule scale, so not many people would be interested in tinkering with it. But if something goes wrong when someone important is viewing the site, it would be really embarrassing; that's why I;m very concerned about security, and if using only HTML makes its security wafer-thin I would like to reconsider my options. So could someone please shed some light on this matter? (ooh it's been a while since I used that phrase

)
HTML doesn't affect security in any way. Your site is as secure as your FTP password.
PHP makes a site much less secure (if coded badly).
