No worries.
First you have to REALIZE what compiling and development tools mean/do. By default, SME Server does not hold anything that can endanger the stock stability and security. By adding development tools to be able to compile software from source, you are breaking this default status.
After adding development tools and compiling the software you want, you should remove all the developemnt tools to gain back 'safe' status.
BUT, it is recommended in general NOT to install developement tools at all on a SME server, but instead use a seperate (virtual) machine for that and copy over the compile results.
Since you have no experience in this field, I strongly suggest that you go through the wiki and forums in search for any information regarding compiling things on SME Server. I could give you the 1 liner command, but that would prevent you from reading real important stuff, and you ARE raising your knowledge bar by becoming a developer from the status of that of a happy user.
Don't worry, it can be done, but please take the learning curve for you own security and stability.
