Well worth reading the link posted by songdogtech and then when you’re ready you can head over to the “famous 5 minute install” and follow the instructions there. It’s actually simpler that it at first might seem, at least once you have the fundamentals in place such as a server (or hosting account) to install it on and an FTP application to upload the files.
However, if you have a standard hosting account somewhere which also includes some kind of web based control panel (cPanel for example) there’s a good chance you will find a button somewhere on that panel to install WordPress for you – then you don’t need to upload anything, just click the button and off you go!
In fact instructions for that kind of automated install method can be found here so check with your host if that is available as it will save you a bit of time.
