Use MQL4 language in custom charting software

Hello! I do not know if it is even possible, but is there a way to use custom written indicators from MetaTrader 4 (MQL4 / MQ4) in other custom made charting software? I am a noob regarding coding and only able to code some simple MT4 indicators. But i can imagine that, nowadays, it would be somehow possible to do so. And if, what do i need? Like a core library? And where to get it?

If it is a silly question, pardon me in advance though!
