If your version of Windows 7 is 64 bit, then the only way to run an old DOS game (which is very likely 16 bit) is to use an emulator like DOSbox or an operating system contemporary to the game either in a virtual machine or as a second operating system (installing an older Windows OS next to a newer one that's already installed is very tricky, so the virtual machine would be much easier.)
As to how the game would look, I would venture to say that your best bet would be to use DOSbox. Running an older OS in a virtual machine or as a second operating system might be ugly looking since it's unlikely that video drivers exist for your hardware that are compatible with a very old version of Windows like Windows 98.
DOSbox isn't really all that hard to use once you get used to it.
