There is almost nothing that hos not yet been programmed for MT4/5 - do you know that?

So here is a series of articles with code and examples about panel - just for you (and others) to past and copy what you need:

In this article, I will continue the development of the ProgressBar control. In particular, I will create the functionality for managing the progress bar and visual effects.
