How to properly design a simple application?

Question

C++ / C#

Hello. I looked at many examples and books, but still - how to design an application correctly? What components to use, how it is more convenient to arrange, how to find out on the basis of which component you can make a filter? Here I wrote a simple online radio -
yes it works, but I want to make it like PCRadio, or some other online player with a choice of genre and other things. I do only "for myself", I study.

Looks cool.
In general, about the location. There is such a layout tab, use the components from it for layout.
Also look towards the Dock property. It allows you to bind to a parent container.
Appearance. Unfortunately, WinForms is very limited in the appearance of controls, although there is a custom render, it might be worth switching to WPF.
The filter is usually done based on a user control. Inside is an ordinary text box, a button with a magnifying glass, a clear button. Items - Bindable collection list of elements to filter Query - entered query
QueryChanged - event that occurs when the query changes QueryItemSelected - Selecting an item from the list
