There are some things that you can not just copy and paste. There is some code that is worked out on the server side of things that you will not see on the client side. (Somebody correct if I am wrong but I want to say PHP is one of those languages that you will never see on the client side).
Nothing is impossible to learn, it just comes down to how much time you are willing to dedicate (or sacrifice if you're short on time). Honestly, you might find that Visual Studio's .Net platform might be easier to learn than something like JSP or PHP. Either way there will be some real effort involved. If you're short on time, I would recommend contacting a local college for some 'volunteer' work. A lot of students need some sort of internship for their degree. Or you might find that there is someone willing to work for cheap.
For a little bit of reference, I've been web developer student for a little over 2 years and I am now striking out as a 'freelancer'. And to be honest, I'm nervous. It's been too easy to underestimate how much work actually goes into coding a project. I know that I've learned more from doing websites for people than I did in school. But, it would have been VERY difficult to accomplish what I have without the training.
Best advice is get into it and learn a little more about it. You may find that you might be able to accomplish what you need to with just some HTML. In the very least, it will give you a frame of reference.
I hope this helps.
